Properties of Waves - Science 7th

Front

What happens to the frequency of a wave if the wavelength increases?

Back

The frequency decreases.

Front

What type of wave can travel through matter and empty space?

Back

Electromagnetic wave.

Front

In which medium do mechanical waves travel fastest?

Back

Solids.

Front

In a longitudinal wave, how do the particles move as the wave travels?

Back

The particles move parallel to the wave's motion.

Front

What type of wave is characterized by particles moving perpendicular to the wave's motion?

Back

Transverse wave.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second.

Front

Explain the difference between mechanical and electromagnetic waves.

Back

Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is an example of a transverse wave?

Back

Light waves are an example of transverse waves.

Front

What is an example of a longitudinal wave?

Back

Sound waves are an example of longitudinal waves.
