Waves

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium. They include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which mediums can sound waves travel through?

Back

Sound waves can travel through solids, liquids, and gases.

Front

What does the letter 'A' typically represent in wave diagrams?

Back

The letter 'A' typically represents the amplitude of the wave.

Front

What is the definition of a wave?

Back

A wave is a regular disturbance that carries energy through matter or space.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through (e.g., sound waves), while electromagnetic waves do not require a medium and can travel through a vacuum (e.g., light waves).

Front

What is wavelength?

Back

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

Front

What is amplitude in the context of waves?

Back

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

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particle displacement is perpendicular to the direction of wave propagation, such as in electromagnetic waves.
