| 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.
🗑
