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

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.
