## Top best answers to the question «Can we detect gravity waves»

Gravitational waves can be detected indirectly – by observing celestial phenomena caused by gravitational waves – or more directly by means of instruments such as the Earth-based LIGO or the planned space-based LISA instrument.

FAQ

Those who are looking for an answer to the question «Can we detect gravity waves?» often ask the following questions:

### 👋 Can we see gravity waves?

Gravitational waves are invisible. However, they are incredibly fast. They travel at the speed of light (186,000 miles per second). Gravitational waves squeeze and stretch anything in their path as they pass by.

### 👋 Can you attract electromagnetic waves with gravity?

• You can attract electromagnetic waves with gravity. Any mass will do so. However, unless you have a black hole or something of similar mass, you are unlikely to be able to do so to any significant and useful way. Note that you cannot attract electromagnetic waves with magnets.

### 👋 Do gravity waves have a frequency?

• Gravity doesn't have a resonant frequency. Resonant frequencies are properties of objects, not waves. For example, an instrument can be tuned to resonate strongly at some particular frequency.

### 👋 Does gravity affect wifi waves?

General relativity describes gravity as the effect of a curved space-time on moving particles. Radio waves are affected by gravity the same way as light is affected - the only difference is, light is visible to us.

### 👋 How do scientists detect seismic waves?

• Scientists can detect seismic waves by using a seismograph, they use the results to predict the possibility of an earthquake. Seismic waves spread out from the focus, which is where the earthquake starts. This is where most damage is done when the earthquake happens on land.

### 👋 How do we detect gravitational waves?

• Since the 1960s, various kinds of gravitational-wave detectors have been built and constantly improved. The present-day generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves from astronomical sources, thus forming the primary tool of gravitational-wave astronomy .

### 👋 How do we detect sound waves?

• Sound waves can cause some objects to vibrate, allowing for detection of the sound. The vibrations from the sound waves must be converted into a signal—usually an electrical signal—and then amplified and processed. Your ear and a microphone are common detectors of sound.

### 👋 How do you detect matter waves?

In the Davisson–Germer experiment, electrons are scattered off a crystalline nickel surface. Diffraction patterns of electron matter waves are observed. They are the evidence for the existence of matter waves. Matter waves are observed in diffraction experiments with various particles.

### 👋 How do you detect radio waves?

A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies.

How do you detect sound waves?

We can detect sound using our ears. An ear has an eardrum inside, connected to three small bones. The vibrations in the air make the eardrum vibrate, and these vibrations are passed through the three small bones (called ossicles) to a spiral structure called the cochlea.

What causes waves gravity?

Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe… The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae (massive stars exploding at the end of their lifetimes), and colliding neutron stars.

What waves can telescopes detect?
• Optical telescopes observe visible light from space…
• Objects in the universe emit other electromagnetic radiation such as infrared , X-rays and gamma rays.
What waves can your senses detect?

Human senses include the ability to detect electromagnetic waves in the 3800-7600 angstrom range, air waves of 15 to 20,000 beats per second, air-borne and liquid-borne molecules of proper size, quantity and configuration, and to generate nerve impulses triggered by objects impinging on body surfaces with enough force, ...

When did ligo detect gravitational waves?
• The improved detectors began operation in 2015. The detection of gravitational waves was reported in 2016 by the LIGO Scientific Collaboration (LSC) and the Virgo Collaboration with the international participation of scientists from several universities and research institutions.

### Video answer: Why can't ligo detect mergers of supermassive black holes?

Why it is so hard to detect gravity wave?

#### How do we know gravitational waves are hard to detect?

• The waves are then very weak by the time they reach Earth. This makes gravitational waves hard to detect. How do we know that gravitational waves exist? In 2015, scientists detected gravitational waves for the very first time. They used a very sensitive instrument called LIGO (Laser Interferometer Gravitational-Wave Observatory).
