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?
Homework Answers
Yes, the ratio of the angle of incidence to the angle of refraction is always constant for specific pair of media. (i.e its always constant for pair of air and water) But it will be different for different pair of media.
will the angles themselves be in constant ratio, NO, it need not to be true for all values of angles.
is the path of light through water (or plastics) the same when it’s direction is reversed? Yes, it is known as law of reversibility. a ray will trace the same path if its direction is reversed, But the pair of media should be same.

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...

I'm currently studying for my physics final right now and I could use some help. Here's three questions for you that are unrelated to each other. 1) A diver in the water shins light up at an angle underneath a thick glass bottom boat. At what angle would none of the light be observed by someone standing in the boat? 2) The central peak of a pattern formed by a slit that is 42.5 um wide has a width of...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...

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...

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...

4. Pretend you tip the apparatus up at an angle so that the face of the Helmholtz coil is parallel to the direction of the earth's magnetic dip angle. (By "face of the Helmholtz coil" we mean the Area Vector is parallel to Earth's Magnetic Field Vector.) The controls are now pointed up into the air . What would the effect be on the beam of electrons? (Assume you have not changed V or I.) a) The diameter would decrease....
