Physics-chapter 9: general waves properties

what is wave speed?

Wave speed is the speed at which a wave travels through a medium, determined by the type of wave and the properties of the medium.

what is wave front"?

A wave front is an imaginary surface representing points of a wave that oscillate in phase, indicating the same stage of a wave's cycle.

what is frequency in waves?

Frequency in waves refers to the number of complete cycles or oscillations that occur in a unit of time, typically measured in hertz (Hz).

what is a transverse wave

A transverse wave is a type of wave where the oscillation or displacement of the medium is perpendicular to the direction of wave propagation, commonly observed in waves on a string or electromagnetic waves.

what is wavelength?

Wavelength is the distance between consecutive points of a wave that are in phase, such as from crest to crest or trough to trough, and is typically measured in meters.

what is the crest in waves

The crest in waves is the highest point of a wave, representing the maximum displacement of the medium from its rest position.

what is the troughs in waves?

The troughs in waves are the lowest points of a wave, indicating the maximum downward displacement of the medium from its rest position.

What is a longitudinal wave?

A longitudinal wave is a type of mechanical wave in which the particles of the medium move parallel to the direction of the wave's propagation, resulting in areas of compression and rarefaction.

what is formula for wavelength

The formula for wavelength is defined as the distance between consecutive crests or troughs in a wave, typically represented by the symbol λ (lambda). It can also be calculated using the speed of the wave divided by its frequency.

what is formula of wavespeed

The formula for wave speed is given by the equation v = fλ, where v is the wave speed, f is the frequency, and λ (lambda) is the wavelength.

what will cause a change in the frequency of a wave?

Changes in the medium, the speed of the wave's propagation, or alterations in tension can all cause a change in the frequency of a wave. Additionally, the Doppler effect describes frequency changes due to the relative motion between the source and the observer.

what is the movement of a transverse wave

Transverse waves move perpendicular to the direction of wave travel, with oscillations occurring up and down or side to side, creating crests and troughs.

what is the movement of a longitudinal wave

Longitudinal waves move parallel to the direction of wave travel, with oscillations occurring in compressions and rarefactions.

what is the formula for displacement in waves?

The formula for displacement in waves is typically represented as y(x,t) = A sin(kx -  t + ), where A is amplitude, k is the wave number,  is angular frequency, and  is the phase shift.

What is the formula for amplitude in waves

The formula for amplitude is A = max(y) - min(y) / 2, where max(y) is the maximum displacement and min(y) is the minimum displacement of the wave.
