What are the 5 parts of the wave?
Vocabulary
- crest. the top of a wave.
- wave. moving swell on the surface of water.
- wave height. the distance between a wave’s trough and crest.
- wavelength. the distance between the crests of two waves.
- wave trough. the lowest part of a wave.
What are two main types 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.
What is the middle line of a wave called?
Graphing a Wave In this picture you can see that the highest point on the graph of the wave is called the crest and the lowest point is called the trough. The line through the center of the wave is the resting position of the medium if there was no wave passing through.
What is one cycle of a wave?
One cycle of a wave is one complete evolution of its shape until the point that it is ready to repeat itself. The period of a wave is the amount of time it takes to complete one cycle. Frequency is the number of complete cycles that a wave completes in a given amount of time.
What are the 4 main parts of a sound wave?
There are four main parts to a sound wave: wavelength, period, amplitude, and frequency.
How fast a wave travels is called?
Cards
| Term wave Speed | Definition A measurement of how fast a wave travels through a medium. Measured by measuring the distance a given point on the wave travels in a certain amount of time. S=d/t |
|---|---|
| Term wave | Definition A disturbance that transfers energy from one location to another as it travels through a medium. |
Which wave carries the most energy?
Gamma rays
Does wavelength affect speed?
The wavelength of a wave does not affect the speed at which the wave travels. Both Wave C and Wave D travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.
What happens if you increase the wavelength of a wave?
The distance from one crest to the next is called a wavelength (λ). The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease.
Why do shorter wavelengths refract more?
As the wavelength of light decreases, the amount of refraction increases. Shorter light wavelengths (such as violet and blue) are slowed down more and hence have more bending than the longer wavelengths (such as orange and red).
Which color of light has the greatest period?
Violet waves
