My question is related to Optics- Interference from thin films: If we wish to coat flat glass [ index of refraction (n)=1.50] with a transparent material (n =1.25) so that reflection of light at wavelength 600 nm is eliminated by interference.What minimum thickness can the coating have to do this? I know that the waves will experience a phase change of pi rad or (0.5 wavelength) since the first medium has a small index of refraction. How does this connect...

Question 5:
How would dust and oil on the glass plates affect the
results?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...

please help with both pages. thank you in advance.
1. Why is the wave model, not ray model, of light is accurate when discussing diffraction and interference? 2. Describe the effects of diffraction; the bending of light waves, as an aperture (opening) becomes smaller and approaches the wavelength of the light source 3. Describe the phase condition for two waves to create constructive interference. Write the mathematical expression for location of interference maximas 4. Describe the phase condition for two...

3. In this diagram, the paths taken by light striking point B on the screen are shown. Laser beam B screen a) Is the distance traveled by light from the upper and lower slits the same in this case? Which path is longer? b) Suppose that the upper path distance is ml., where m is some integer. Assume that the lower path distance is longer than the upper path by an amount exactly equal to 1/2. In the boxes below,...
