Mirrors _____ light and different mediums ______ light

Mirrors REFLECT light and different mediums REFRACT light

100
This wave type has the lowest frequency that we know of. Their wavelength can be as long as a planet and as short as a meter. They can transmit through walls due to this.
Radio waves
100
This color has the highest energy, highest frequency, and shortest wavelength
violet

This kind of light behavior causes the Moon to shine
Reflected
200
If an object lets some light pass through, it's called ______.
translucent
200
This is object breaks up white light in to the visible light spectrum through refraction
A prism
200
This part of the spectrum is directly related to thermal (heat) energy. It has a lower frequency compared to visible light, and it is used in remote controls.
Infrared waves

What cause the sky to be blue? 

Rayleigh scattering 

500
The lower the frequency the _________ the wavelength and the _______ energy.
the LONGER the wavelength and LESS energy
