We are doing a refraction lab and I need help answering a question: we shined a light through a piece of glass shaped in a semicircle through the FLAT side, and recorded the angles of incidence and refraction. My question is, would the path of the light through the plastic be the same when the direction is reversed ( light shine through the curved side). I know there’s a law of reversibility but does it apply if the plastic is shaped like a semi circle?
Homework Answers
Yes, it will also apply if the plastic is shaped like a semi-circle or any media. But the point to be remember is you should not change the point of incidence (the point on the surface seperating two media). If the point of incidence is altered, the path of ray may change.

We are studying refraction right now and I’m wondering does the ratio of the angle of incidence to the angle of refraction remain constant? I know the SINES of the angles will have a constant ratio but will the angles themselves be in constant ratio or not? Also, is the path of light through water (or plastics) the same when it’s direction is reversed?

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...

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...

We will be looking at the movement of light along straight lines using the optics bench. You've most likely also used a mirror to see yourself or other things by way of their reflected image. In fact, everything you see is based on the light that bounces off or travels through the material between you and the object you're looking at. This is why it's harder to see detail or distance...

I don't understand Question 5-9
Any information on how to answer these?
The speed of light depends on the medium through which it travels, and it is generally slower in the denser media. Fermat's principle in optics asserts that light travels from one point to another along a path for which the time of travel is minimum. In a uniform medium, where the speed of light remains constant, "shortest time" means "shortest path", and the ray of light follows a...

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...
