Electromagnetic Waves and Their Properties

Front

What is the formula to calculate the velocity of a wave?

Back

Velocity (v) = Wavelength (λ) × Frequency (f)

Front

Define wavelength in the context of electromagnetic waves.

Back

Wavelength is the distance between two consecutive crests or troughs of a wave, typically measured in meters.

Front

What is frequency in relation to electromagnetic waves?

Back

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

Front

How do you calculate the wavelength if you know the velocity and frequency?

Back

Wavelength (λ) = Velocity (v) / Frequency (f)

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 × 10^8 m/s.

Front

Identify the part of a wave that represents the highest point.

Back

Crest.

Front

Identify the part of a wave that represents the lowest point.

Back

Trough.

Front

What type of electromagnetic waves are used for sterilizing medical equipment?

Back

Ultraviolet (UV) waves.

Front

Which electromagnetic waves are commonly used for television broadcasting?

Back

Radio waves.

Front

What is amplitude in the context of waves?

Back

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