Light and Waves Review

When two or more waves meet and​ (a)   the resulting waveform will be the​ (b)   of the individual waves. Although there is a different displacement as the waves are superimposed, passing through each other does not alter the​ (c)   ,​ (d)   or​ (e)   of the individual waves

• Light is a transverse wave. 

• Light can travel through the vacuum of space

• The speed of light changes in a vacuum

• Light travels through an aether

• Light propagates from changing electric and magnetic fields.

• The speed of light in a vacuum depends on its wavelength.

The velocity of waves in a particular string at constant tension is 78 m s−1. The string is fixed at both ends. If a particular frequency of a standing wave formed in the string is 428 Hz, how far apart (in cm) would two adjacent antinodes be? State your answer correct to 2 significant figures.

The following diagram shows the standing wave pattern made by a rope when it is oscillated back and forth.

If the length of the rope between the hand and the hook securing the end is 0.90 m, what is the wavelength (in m) of the standing wave shown? State your answer correct to 2 significant figures

The following diagram shows the standing wave pattern made by a rope when it is oscillated back and forth.

If the velocity of the wave is 200 ms−1, what is the frequency of the wave shown (in Hz) in the image? State your answer correct to 3 significant figures.

The following diagram shows the standing wave pattern made by a rope when it is oscillated back and forth.

What is the fundamental frequency (in Hz) of this string? State your answer correct to 3 significant figures.
