How Can An Object Emit More Than One Type of Radiation and Which Animals Can See Ultraviolet Radiation?

Many objects usually emit more than one type of radiation simultaneously.

For instance, the Sun radiates everything from gamma rays to radio waves.

People emit radio waves, but we can’t detect those waves without the proper receiving equipment.

You’d have to use a radio telescope to do so, but all the other radio waves bouncing around Earth’s surface would get in the way.

Scientists believe that some animals see types of radiation other than light.

Snakes and bumblebees may see ultraviolet radiation, and bats may see infrared radiation.
