1. Two source, S1 and S2, are vibrating in phase and produce waves with a wavelength of 2.5 m. The two waves overlap at a nodal point. Calculate the smallest corresponding difference in path length for this point. [ans: 1.2m]
2. A point on the third nodal line from the center of
an interference pattern is 35 cm from one source and 42cm from the
other. The sources are 11.2 cm apart and vibrate in phase at
10.5Hz.
a) calculate the boyfriend of the waves [ans: 2.8cm]
b) calculate the speed of the waves [29cm/s]
3. Thomas Young showed that light passing through 2 parallel narrow slits produces a pattern of light and dark fringes. Did this support or contradict Newton's corpuscular theory of light? Explain your answer.
Ps. Plz explain your solutions so that I can follow up
with these steps.
