Waves

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its wavelength, frequency, and amplitude.

Front

What is wavelength in the context of waves?

Back

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

Front

What does amplitude represent in a wave?

Back

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

Front

How is frequency defined in wave mechanics?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa, according to the wave equation: speed = wavelength × frequency.

Front

What is the medium in the context of wave propagation?

Back

A medium is the substance or material through which a wave travels, such as air, water, or solid materials.

Front

Why can't sound be heard in outer space?

Back

Sound cannot be heard in outer space because there is no medium (like air) to carry the sound waves.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel (e.g., light waves), while longitudinal waves have oscillations parallel to the direction of wave travel (e.g., sound waves).

Front

What is the formula for calculating wave speed?

Back

Wave speed can be calculated using the formula: speed = wavelength × frequency.

Front

What is constructive interference in wave behavior?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.
