1. Two source, S1 and S2, are vibrating in phase andproduce waves with a wavelength of 2.5 m. The two waves overlap ata nodal point. Calculate the smallest corresponding difference inpath length for this point. [ans: 1.2m]
2. A point on the third nodal line from the center ofan interference pattern is 35 cm from one source and 42cm from theother. The sources are 11.2 cm apart and vibrate in phase at10.5Hz.
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 2parallel narrow slits produces a pattern of light and dark fringes.Did this support or contradict Newton's corpuscular theory oflight? Explain your answer.
Ps. Plz explain your solutions so that I can follow upwith these steps.
