### ☑️ Can a eeg brain wave study detect epilepsy?

EEG studies are used to monitor brain wave activity. It can detect abnormalities in such brain waves. So it can be used to detect epilepsy. However, epilepsy is diagnosed when someone has recurring seizures. It is possible that someone can have unusual activity, but not have any seizures. So normally people will have had seizures before having a EEG study. The EEG study can help to find where the problem may lie.

### ☑️ Does wave spike mean seizuzre is going on?

Spikes or sharp waves are terms commonly seen in EEG reports. If these happen only once in a while or at certain times of day, they may not mean anything. If they happen frequently or are found in specific areas of the brain, it could mean there is potentially an area of seizure activity nearby.

### Compare and contrast a transverse wave and a compressional wave?

Compressional waves are closer together, transverse waves are farther apart. They are both mechanical waves. In compressional waves the medium moves forward and backward along the direction a wave travels. While, transverse waves the wave energy causes matter in the medium to move up and downor back and forth at right angles to the direction thw wave travels. Hope I helped! :) <3

### What is wave and types of wave?

Types and features of waves

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium… The height of a wave is the amplitude.

### What is longitudinal wave and transverse wave?

• In a longitudinal wave, the medium or the channel moves in the same direction with respect to the wave. Here, the movement of the particles is from left to right and force other particles to vibrate. In a transverse wave will the medium or the channel moves perpendicular to the direction of the wave.

### What is square wave and sine wave?

• While a sine wave has a single frequency in it a square wave contains many higher frequencies as well, called harmonics, which can cause buzzing or other problems with some equipment. Square wave output is found only in the cheapest equipment and should be avoided if possible. This waveform is a compromise between the sine wave and the square wave.

### What are wave length and wave height?

Wave length, also known as cycle and period, is the difference in magnitude from one point on a wave to the corresponding point on an adjacent wave as measured along, and defined by, the x-axis of the graphed wave forms. Wave height, also known as magnitude, is the distance above or below the x-axis as measured along, and defined by, the y-axis of the graphed wave forms.

### Is deep wave and water wave the same?

#### How does a wave work in deep water?

• In deep water, longer period waves propagate faster and transport their energy faster . The deep-water group velocity is half the phase velocity. In shallow water, for wavelengths larger than twenty times the water depth, as found quite often near the coast, the group velocity is equal to the phase velocity.

### Relationship between frequency wave length and wave speed?

The wavelength is equal to the speed divided by the frequency.

### Can p wave and t wave occur simultaneously?

#### What does it mean when a T wave is negative?

A bow wave is produced by overlapping circles that form a V, a shock wave is produced by overlapping spheres that form a cone.

### What's the difference between sine wave and ring wave?

• The difference with ring modulation is that neither of the input signals, carrier or program, appear at the output. Therefore, ring modulation of two sine waves having frequencies of 1,500 Hz and 400 Hz, would produce two signals: one at 1,900 Hz, and one at 1,100 Hz.

### How are wave equations, wave functions and orbitals related?

• WAVE EQUATIONS, WAVE FUNCTIONS AND ORBITALS According to the quantum mechanical concept, electrons in atoms and molecules are considered as ‘standing waves’ or ‘stationery waves’ (similar to vibrations in a stretched string, but in 3 dimensions). Properties of a wave Consider a standing wave in a stretched string.

### What's the difference between a wave and a wave?

• According to the definitions of them, they are almost the same. In the websites I looked at, the difference between them was described by examples which not reflect the difference itself. Both terms describe disturbances in some medium. Wave usually refers to a continuous disturbance.

### A sound wave and a light wave have identical?

• Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. What do light waves and sound waves have in common? Sound and light are similar in that both are forms of energy that travel in waves.

### How much time between p wave and s wave?

• Travelling waves transport energy from one area of space to another, whereas standing waves do not transport energy. Also, points on a standing wave oscillate in phase, whereas on a travelling wave only points a wavelength apart oscillate in phase - the rest on that wavelength oscillate out of phase with the original point.

### What's the difference between wave speed and wave frequency?

• The wave frequency is a property determined by the source of the wave. For waves such as light and sound, the frequency of a wave stays the same regardless of the medium it travels on. Wave velocity is the speed the wave propagates in a medium. Wave velocity is a property of the medium.
