A stack about waves
Question | Answer |
---|---|
What is a wave? | Rythmic didturbances that carry energy without carrying matter. |
What is a mechanical wave? | Types of waves that require matter to transfer energy. |
What happens in a transverse wave? | The wave energy causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels. |
What happens in a compressional wave? | Matter in the medium moves forward and backward along the same direction that the waves travel. |
What is an electromagnetic wave? | Waves that can travel through space where there is no matter. |
What is the amplitude of a transverse wave? | One- half the distance between the crestand the trough. |
When is the amplitude of a compressional wave greater? | Rythmic didturbances that carry energy without carrying matter. |
What is a mechanical wave? | It is the distance between the top of two crests or the distance between the bottom of 2 troughs. |
What is the wavelegnth of a compressional wave? | The distance between the center of a compression to the next, or the distance between the center of a refraction to the next. |
What happens in a compressional wave? | The number of wavelegnths that pass a given point in 1 s. |
What is Reflection? | It is when a wave strikes a surface and bounces off. |
What is Refraction? | The bending of a wave as it moves from one medium to another. |
What is Diffraction? | The bending of waves around a barrier. |
What is interference? | The ability of two waves to combine and form a new wave when they overlap. |
