The Nature of Waves: Properties of Waves

The video tutorial explains the characteristics of waves, focusing on amplitude, wavelength, and frequency. It describes how amplitude indicates the energy of a wave, with higher amplitude waves having more energy. Wavelength is defined as the distance between two adjacent crests or troughs, while frequency is the number of complete waves passing a point in a given time. The tutorial uses examples to illustrate these concepts, such as comparing wave amplitudes and demonstrating frequency changes by moving a rope at different speeds.

What are the high points of a transverse wave called?

• Troughs

• Crests

• Nodes

• Antinodes

How is the amplitude of a wave determined?

• By measuring the distance between two crests

• By measuring the distance from the resting point to a crest or trough

• By counting the number of waves passing a point

• By measuring the distance between a crest and a trough

Which wave property indicates the amount of energy a wave has?

• Velocity

• Amplitude

• Frequency

• Wavelength

What is the distance between two adjacent crests called?

• Frequency

• Amplitude

• Wavelength

• Period

What happens to the frequency of waves when the rope is moved more quickly?

• The frequency decreases

• The frequency remains the same

• The frequency increases

• The frequency becomes zero
