Q1) A point on the third nodal line from the center of an interference pattern is 36.2 cm from one source and 30.7 cm from the other. The sources are 12.3 cm apart and vibrate in phase at 10.6 Hz. Calculate the wavelength of the waves, in cm.
Q2) Light from a medium with index of refraction n1=1.33 passes into a medium with index of refraction n2. If it entered at an angle of θ1=26°, and exited at an angle of θ2=19°, what would be the value of n2? (IMAGE ATTACHED)
