Light interactions
100
This type of wave needs a medium
mechanical wave
100
This is one complete back and forth motion of an object
What is vibration
100
What is the light doing?
scattering/refracting
100
True/False: All EM waves do not require a medium to travel in.
What is true
100
This is the bouncing back of rays of light, sound or heat
What is reflection
200
X-rays and microwaves are examples of these types of waves
What is electromagnetic
200
this is any substance through which a wave can travel
What is a medium
200
How many waves are in the diagram below?
What is 3
200
Which wave contains the highest frequency?
What is gamma
200
This is the bending of a wave as it passes between two substances
What is refraction
300
This is any disturbance that transmits energy through matter or empty space
What is a wave
300
This is the highest point of a transverse wave
What is a crest
300
If the bottom indicated a sound wave, which letter is the rarefraction?
What is P
300
Which wave is used for wifi and cell phones?
What is microwaves
300
Light goes completely through - like a glass, or window
What is transparent
400
Label the parts of a wave on your desk:
Wavelength, crest, trough, amplitutude
Wavelength, crest, trough, amplitutude
400
This is the lowest point of a transverse wave
What is a trough
400
What is the wavelength of the wave?
What is 4 cm
400
Which 3 waves can cause cancer or tissue damage?
What is Gamma, x-ray, and uv
400
When light CANNOT pass through a material
What is opague
500
What is the speed of a sound wave that has a wavelength of 2m and a frequency of 5Hz?
Wave speed = wavelength x frequency
10
500
This is what electromagnetic waves can travel through. Another word for empty space
What is a vacuum
500
What can you conclude about the graph?
What is the FASTER the wave speed increases, the LONGER the wavelength.
500
What color stars are the hottest?
What is blue
500
Scientifically explain WHY the color black gets hottest in the sun and white is the coolest. Hint; Use the words energy and heat in your answer.
What is since white reflects light, no energy is being absorbed so it is cooler, opposite for black- all that energy is heat!
