Electromagnetic / Mechanical Waves

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without the transfer of matter.

Front

What is a medium in the context of sound waves?

Back

A medium is the substance through which sound waves travel, such as air, water, or solids.

Front

What type of waves are used in radio broadcasting?

Back

Radio waves are used in broadcasting to transmit audio and data over long distances.

Front

What type of energy can travel through a vacuum?

Back

Electromagnetic energy can travel through a vacuum, unlike sound which requires a medium.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the wavelength of a wave?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest.

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and consist of oscillating electric and magnetic fields.
