100
Waves carry __________
What is energy?
100
I have the longest wavelength on the spectrum
What is radio waves?
100
If a shirt reflects all colors, what color is the shirt?
White
100
The distance from crest to crest or trough to trough
What is wavelength?
100
What type of wave is a sound wave?
longitudinal or mechanical
200
This type of wave vibrates matter in the opposite direction from how the wave is moving.
What is a transverse wave?
200
What is the only electromagnetic radiation (light wave) you can see?
What is visible light?
200
What is a medium? Give an example. What happens when a wave moves from one medium to another. What is it called?
material that mechanical wave needs to travel through.
solid, liquid, Gas
Waves bend when they move from one medium to another. It is called refraction.
200
What is the height of a wave from resting position is known as?
amplitude
200
What is resonance? Give an example.
Resonance occurs when an object is subjected to an vibration that matches its natural frequency and it also vibrates. A tuning fork vibrating near another tuning fork of the same size is an example.
300
This type of wave does not need matter to transfer energy.
What is an electromagnetic wave?
300
On the electromagnetic spectrum, what happens to the energy as we move from gamma waves to radio waves?
What is the energy decreases?
300
What causes an echo?
An echo is caused by sound waves bouncing off a smooth surface and reflecting back.
300
What happens to the frequency and energy of a wave when the wavelength gets longer?
Frequency becomes lower; energy becomes lower
300
Sound waves travel the fastest in what medium? The slowest in what medium?
fastest- solids
slowest- gases
400
High frequency waves have _______ wavelengths.
What are SHORT wavelengths?
400
Pick two types of electromagnetic waves and give a use of each.
400
What happens when pure white light waves pass through a red filter?
When white light passes through a red filter all of the other colors in the spectrum are absorbed and only red light passes through it. Only red can be seen. All other colors appear shades of black.
400
What properties of a wave can you tell if a wave has a high amount of energy?
High frequency or high amplitude
400
Explain why sound waves travel the fastest in solids.
solids: particles very tightly packed therefore sound waves can vibrate off of the particles very quickly.
500
Draw a standing wave. Label the the nodes and antinodes.
500
Draw the electromagnetic spectrum going from radio waves to gamma waves. Label all 7 types of waves. Make directional arrows to show low frequency to high frequency.
500
What happens when the crest or one wave meets the crest of another wave moving in the opposite direction?
The crests will momentarily combine and create a wave with the combined amplitude of both crests, then each wave will continue moving in the direction it was going.
500
The number of wavelengths that pass a given point per second.
What is frequency?
500
Explain why you will never hear an explosion in space
what is because space is a vacuum and there are no particles for the sound to travel through
