A student is using a color filter in his experiment. What would be true if she was using a blue color filter?
The color filter will only absorb green light.
Objects seen through a green filter will look blue if the objects absorb blue light
Non-blue objects will appear black because other wavelengths are absorbed by the filter

What statement is true about blue light as compared to red light.
Blue light has longer wavelengths, lower frequencies, and higher energy.
Blue light has longer wavelengths, lower frequencies, and lower energy than red light.
Blue light has shorter wavelengths, higher frequencies, and higher energy than red light.
Blue light has shorter wavelengths, higher frequencies, and lower energy than red light.
Two waves are traveling toward each other. What will happen when the two waves meet?
Constructive interference will cause the resultant wave height to double
Constructive interference will cause the resultant wave height to remain the same.
Destructive interference
Which range of the wavelengths can the human eye see?

What happens when a sound wave touches an object?
The sound wave is refracted by the object.
The sound wave is reflected by the object, causing an echo
The sound wave is absorbed by the object, increasing volume.
