Energy and Waves Flashcard

Front

What is Refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in their speed.

Front

What happens to ocean waves as they approach shallower water?

Back

Ocean waves slow down and change direction due to the force exerted on them by the seabed.

Front

What is the relationship between frequency and wavelength in waves?

Back

Higher frequency waves have shorter wavelengths, while lower frequency waves have longer wavelengths.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

How is Kinetic Energy converted to Potential Energy?

Back

Kinetic energy is converted to potential energy when an object moves against a force, such as a roller coaster climbing a hill.

Front

What is Reflection in the context of waves?

Back

Reflection is the bouncing back of waves when they hit a barrier or surface.

Front

What principle do bats use to navigate?

Back

Bats use the principle of reflection by emitting high-pitched sounds that bounce off objects to determine their location.

Front

What is an Electrical Motor?

Back

An electrical motor is a device that converts electrical energy into mechanical energy using magnetic forces.

Front

What is the difference between Radio Waves and Microwaves?

Back

Microwaves have a higher frequency than radio waves, which means they have shorter wavelengths.
