Mechanical and Electromagnetic Waves

Front

What is the definition of amplitude in the context of waves?

Back

Amplitude is the maximum distance that a wave displaces a medium from its rest position.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel, while electromagnetic waves do not require a medium and can travel through a vacuum.

Front

What is wavelength?

Back

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

Front

What is frequency in relation to waves?

Back

Frequency is the number of complete wave cycles that pass a given point in one second, measured in Hertz (Hz).

Front

How do you calculate the speed of a wave?

Back

Wave speed can be calculated using the formula: Speed = Wavelength × Frequency.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What are some examples of mechanical waves?

Back

Examples of mechanical waves include sound waves, water waves, and seismic waves.

Front

What are some examples of electromagnetic waves?

Back

Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the term for the distance between two consecutive crests of a wave?

Back

The term is wavelength.

Front

What is the significance of the medium in mechanical waves?

Back

The medium is essential for the propagation of mechanical waves, as it is the substance that the wave travels through.
