Grade 10 Science - Wavelength Lab Quiz

Wave

a disturbance that transfers energy from one point to another without transferring matter

Parts of a Wave

Crest: Highest point

Trough: Lowest point

Rest position: Wave has no amplitude

Wavelength: Distance of 1 cycle

Amplitude: Wave height from rest position to top of crest or bottom of trough. Energy transferred by a wave depends on its amplitude. Measured in meters.

Frequency

The rate of repetition of a wave. The amount of crests that pass a point per second. Symbol is f. Measured in hertz(Hz)

Relationship between frequency and wavelength

When the frequency increases, the wavelength shortens. This is an inverse relatinship.

Relationship between frequency, wavelength, and energy

The frequency increases and the wavelength shortens with the increase in energy.

Radio Waves

Long wavelength, low frequency, low energy

Gamma rays

Short wavelength, high frequency, high energy
