Bats have an adaptation called echolocation which helps them locate prey. The bat emits a noise that moves through the air waves, changing the air pressure around it. When the waves hit an object, they then bounce back towards the bat. The bat's brain uses the vibrations to calculate the distance to the object. What kind of energy is the bat using to locate prey?

• Thermal energy

• Sound energy

• Light energy

• Electrical energy

An example of electrical energy is

• cutting paper

• dusting the television

• ringing the doorbell

• playing the drum

How is light energy different from sound energy?

• Light energy moves slower than sound energy.

• Sound energy can pass through opaque (not transparent) objects.

• Sound energy moves faster than light energy.

• Light energy can pass through opaque (not transparent) objects.
