Frequency, amplitude, and wavelength are all properties of waves. Frequency is the number of oscillations per unit time, amplitude is the maximum displacement of the wave from its equilibrium position, and wavelength is the distance between two consecutive crests or troughs of the wave.

Frequency and wavelength are inversely proportional, meaning that as one increases, the other decreases. This relationship is expressed by the equation (v = f \lambda), where (v) is the wave velocity, (f) is the frequency, and (\lambda) is the wavelength.

In a transverse wave, particles vibrate perpendicular to the direction of wave propagation. Examples of transverse waves include electromagnetic waves, such as light and radio waves, and mechanical waves, such as waves on a string.

The crest of a wave is the point where the displacement is maximum. It is the highest point on the wave.

Standing waves are waves that are confined to a particular region and do not propagate. Sound waves in a room are an example of standing waves, as they are reflected back and forth between the walls of the room.

Interference is the transfer of energy from one wave to another. When two waves overlap, they interfere with each other, resulting in a new wave pattern.

Refraction is the change in direction of a wave as it passes from one medium to another. This occurs because the wave velocity changes as it enters the new medium.

Diffraction is the bending of waves around obstacles. This occurs because waves spread out as they pass through an aperture or around an obstacle.

Mechanical waves are waves that require a medium to propagate. Ocean waves are an example of mechanical waves, as they require water to propagate.

Reflection is the phenomenon that occurs when a wave encounters a boundary and bounces back. This occurs because the wave cannot pass through the boundary.

Electromagnetic waves are waves that do not require a medium to propagate. Light waves are an example of electromagnetic waves.

Frequency is the rate at which a wave oscillates. It is measured in hertz (Hz), which is the number of oscillations per second.

Longitudinal waves are waves in which particles vibrate parallel to the direction of wave propagation. Sound waves are an example of longitudinal waves, as particles vibrate back and forth in the direction of wave propagation.

Wavelength is the distance between two consecutive crests or troughs of a wave. It is measured in meters (m).

Surface waves are waves that travel along the boundary between two media. Ocean waves are an example of surface waves, as they travel along the boundary between water and air.
