Define 'wavelength' in your own words, and explain how it relates to the physical appearance of a wave.

Wavelength is the distance between two consecutive crests or troughs of a wave. It visually represents one complete cycle of the wave.

What is the relationship between the frequency and the wavelength of a wave if the wave speed remains constant?

If the wave speed is constant, frequency and wavelength are inversely proportional. As frequency increases, wavelength decreases, and vice versa.

Describe the difference between a transverse wave and a longitudinal wave, providing an example of each.

In a transverse wave, the oscillation is perpendicular to the direction of wave travel (e.g., waves on a rope). In a longitudinal wave, the oscillation is parallel to the direction of wave travel (e.g., sound waves).

Explain how the amplitude of a wave is related to the energy it carries. If the amplitude of a wave is tripled, how does its energy change?

The energy of a wave is proportional to the square of its amplitude. If the amplitude is tripled, the energy increases by a factor of nine (3 squared).

What happens to the intensity of a spherical wave as it moves away from its source? Explain why this occurs.

The intensity of a spherical wave decreases as it moves away from its source. This is because the energy of the wave is spread over an increasingly larger area (the surface area of a sphere), which is proportional to the square of the distance from the source.

Guided Notes

3 key concepts

1
A wave's amplitude is the distance from the peaks to the middle of the wave, while the wavelength is the distance between crests.
2
Transverse waves oscillate perpendicular to the direction of travel, while longitudinal waves oscillate in the same direction as the wave is moving.
3
Constructive interference occurs when waves build on each other, while destructive interference occurs when waves cancel each other out.
