Video answer: Dangers of electromagnetic waves | 9-1 gcse science physics
Top best answers to the question «What is the least dangerous electromagnetic wave»
- What is the least dangerous electromagnetic wave? The Electromagnetic spectrum lists the most powerful EMR, gamma rays, to the least powerful EMR, radio waves. In addition, the highest energy waves (gamma, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths.
Those who are looking for an answer to the question «What is the least dangerous electromagnetic wave?» often ask the following questions:
👋 What electromagnetic wave has the least energy?

👋 Which electromagnetic wave has the least energy?
What is the lowest energy wave?
- In addition, the highest energy waves (gamma, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths. When scientists actually started to look closely at EMR, they discovered that high-energy photons seemed to travel as very tiny waves and also as rays.

We've handpicked 26 related questions for you, similar to «What is the least dangerous electromagnetic wave?» so you can surely find the answer!Which of the electromagnetic waves have the least wavelength?
Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.Which type of electromagnetic waves has the least wavelength?
- Gamma rays are electromagnetic radiations with the shortest wavelengths (less than 10 pm). They are the most penetrating of electromagnetic radiations, and exposure to intense gamma radiation can have a harmful effect on the human body.
If the wave length is 7 times or less than the wave's height, then you should take precautions. For example, using the minimum 30 percent wave height to boat length, if your boat is 40 feet long, then the wave-height danger zone starts at waves 12 feet high (40 x 30).What causes electromagnetic wave polarization?
- According to quantum mechanics, electromagnetic waves can also be viewed as streams of particles called photons. When viewed in this way, the polarization of an electromagnetic wave is determined by a quantum mechanical property of photons called their spin.
How does an electromagnetic wave begin? how does it travel?
- An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave. Beside above, can electromagnetic waves travel through matter?

What causes electromagnetic waves?
- Electromagnetic waves are caused by electronic devices nearby. Tiny electrical currents exist in the human body which can react with the electromagnetic waves. For example, nerves transmit electric impulses to the brain which can later be affected by the electromagnetic wave and have a positive charge.
An electromagnetic wave is a stream of photons which behaves both like waves and particles. They move perpendicular to the direction of propagation. They have 2 mutually perpendicular components of electric and magnetic fields.

An electromagnetic wave, in its simplest description, is a wave that as it propagates keeps converting its magnetic field into an electric field while converting its electric field into a magnetic field.
Visible light is that part of the electromagnetic spectrum that is seen as colours: violet, indigo, blue, green, yellow, orange and red. Blue light has a very short wavelength, and so produces a higher amount of energy.What electromagnetic wave is harmful?
There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic spectrum and can damage DNA or cells directly.

- Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light. The waves have certain characteristics, given as frequency, wavelength or energy.What is electromagnetic wave equation?
What is the formula for electromagnetic waves?
- So our formula for EM waves (in vacuum) is: c=f⋅λ;c=3⋅108m s. The continuum of various wavelengths and frequencies for EM waves is called the Electromagnetic Spectrum. It turns out that the speed of light is also the ratio of the strengths of the Electric and Magnetic fields in an EM wave.
- Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. They are also perpendicular to the direction of the EM wave.
Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields… They are also perpendicular to the direction of the EM wave.What properties describe electromagnetic wave?
Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.What type of wave is electromagnetic wave?
What are the different types of waves in physics?
- Different Types of Waves in Physics With Examples. Waves transport energy without transporting matter. The energy transportation is carried by a disturbance, which spreads out from a source. Basically, there are three types of waves. Mechanical waves, electromagnetic waves, and matter waves.
- Beta rays are not electromagnetic waves Beta rays also known as beta radiation is obtained through the emission of an electron. Beta rays are not electromagnetic waves because they are charged particles and are capable of getting deflected by the magnetic field. These rays are not pure energy as a photon.

Radio waves have photons with the lowest energies. Microwaves have a little more energy than radio waves. Infrared has still more, followed by visible, ultraviolet, X-rays and gamma rays.Are electromagnetic waves more dangerous than other waves?
- Generally, electromagnetic waves, which have higher energy, are more dangerous than those with lower energies. However, to understand which radiation is more harmful, and why it is harmful, we have to know how it transfers energy as it passes through matter.
- (See this figure .) These extremely long wavelength electromagnetic waves (about 6000 km!) are one means of energy loss in long-distance power transmission. This high-voltage traction power line running to Eutingen Railway Substation in Germany radiates electromagnetic waves with very long wavelengths. (credit: Zonk43, Wikimedia Commons)
- Electromagnetic waves are emitted by electrically charged particles undergoing acceleration, and these waves can subsequently interact with other charged particles, exerting force on them. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact.
