Question | Answer |
What is required for a mechanical wave to move? | Matter |
What are the two types of mechanical waves? | Transverse and longitudinal |
What unit of measurement do we use for wavelength? | meters |
Hertz is the unit of measurement for which quantity? | Frequency |
An example which sound will travel than it will travel through water? | Cool Air |
What are the two types of interference? | Constructive and Destructive |
Which characteristic of the wave does interference effect? | Amplitude |
What is the difference between a transverse wave and a longitudinal wave? | transverse wave goes perpendicular to the disturbance, a longitudinal wave goes parallel |
What is the term for a force that creates a wave? | Disturbance |
If two waves interact, and create a bigger wave, what happens? | Constructive Interference |
If I increase the frequency of a wave, what will happen to that waves amplitude? | It will stay the same |
Two waves come together, and create a space that looks like there are no waves. What has happened? | Destructive Interference |
What is the equation for speed? | : Speed= frequency times wavelength |
What happens to a wave when it experiences diffraction? | it spreads out. |
What happens to a wave during refraction? | It bends when entering another medium. |
What is the term for the wave behavior in which a wave bounces off an object? | Reflection |
Please give me an example of reflection in everyday life. | When light bounces off a mirror and it gets in your eyes. |
Please give me an example of refraction in everyday life. | When you put a straw in a glass of water and it gets bended |
What happens to the amplitude of a sound wave as it travels away from it sound’s source? | It decreases because the wave is spreading out. |
If the source of the sound is moving away from you quickly, how will you perceive it? | The pitch gets lower |
If the source of the sound is moving away from you quickly, its pitch will also decrease. What's that called? | The Doppler Effect |
As a wave travels through a medium, what happens to that medium? | A: It vibrates |
In Star Wars, what is so wrong with the pew-pew noise coming from the guns? | There’s nothing for the wave to travel through, so there can be no sound because space is a vacuum. |
