Q

Radio Waves, and Microwaves

A

Radio and Microwaves can both be used for communication, but Microwaves are better because they have a higher energy. Also, they can be used for cooking

Q

Infrared and Visible Light

A

Infrared can be used for thermal energy. Visible Light can be used for seeing everything. The colors of the rainbow (ROY G. BIV) are all based off of the Visible Light.

Q

Ultraviolet Rays and X-rays

A

Ultraviolet Rays can be used for killing bacteria. When someone gets extremely sick, this Ray is used. X-rays can be used for seeing bones. Also, it is used by construction workers to see cracks in structures.

Q

Gamma Rays

A

Gamma Rays are mainly used for killing bad cells. When a person gets cancer, these Rays are used to kill the cells, but they can also kill good cells.
