    Understanding Light Refraction Through Different Mediums

    Hi! I want to ask you something. When the light travels through medium 1, there is reflection of light, so there is energy released, but it needs time the energy to travel through medium 2, right?

    Refraction of Light: Energy Source Puzzle

    I have though of a puzzling part of refraction that has caused a bit of a problem. it is that if the light slows down then where does it get the energy from to speed back up once it has left the medium it was refracted into?

    Please Explain Me Refraction of light

    Please Explain Me Refraction of light ! Helo everyone, I have gone through my textbooks which only comes to the conclusion that since the light travels at different velocity in different medium so it bends at the interfaces. This is something i can't really understand. It doesnot make anything...

    Question on refraction of light

    Homework Statement under what condition is the angle of incidence greater than the angle of refraction?and viseversa? and WHY? AND how come the speed of light slows down when it travels from a less dense to a more dense substance?and vise versa? Homework...

    Connection of General relativity and geometric Refraction of light

    I tried to obtain refraction of light by sun's gravity by substitution of sun's gravitational field by aether with different speeds of light. I do not get right result. Where I am wrong? For light which travel close to the sun by direct trajectory, I get the following speed of light in...

    How Does Light Refraction Affect the Diameter of a Light Cone in a Pool?

    Homework Statement At the shallow end of a swimming pool, the water is 70.0 cm deep. The diameter of the cone of the light emerging from the water into the air above, emitted by a light source 10.0 cm in diameter at the bottom of the pool and measured by an observer on the edge of the...

    Mathematics of refraction of light

    Can anyone please prove that if d1=EF and if d2=EG and angle MEZ=HEF=angle of incidence and angle HEG = angle of refraction. Please! can somebody help me prove that d1/d2=refractive index taking sin i/sin r=refractive index (The glass slab is ABCD and is kept in vacuum)

    Understanding Light Refraction: Why a Ping Pong Ball Looks Bigger in Water

    i need an explanation for this situation. i've inserted an pingpong ball into a glass full with water (the glass is made out of thick glass if it matters somehow?). Now what happened is that the half of the ball that is in the water looks much bigger than the half that is not in the water...

    Learn About Refraction of Light Experiment

    We are learning about refraction of light at school and we did an experiment with a semi circle plexi glass We shone a ray of light at the plexiglass at different angles to find out the different angles of refraction. When we had the semicircle plexiglass upside down, meaning curved part...

    Snells Law and the Refraction of Light

    The drawing shows a rectangular block of glass (n = 1.52) surrounded by liquid carbon disulfide (n = 1.63). A ray of light is incident on the glass at point A with a theta = 23.0° angle of incidence. At what angle of refraction does the ray leave the glass at point B...

    Calculating Pool Depth with 48 Degrees Depression Angle

    An observator is looking at a coin that is located on a swimming pool's floor with a depression Angle of 48 degrees. Knowing that the swimming pool's depth is 2.6 metres, calculate the depth that the observator can see. (Usually when you look at a swimming pool from with a smaller depression...

    Refraction of Light: Understand Physics Behind Bending Light

    Hi I have a good understanding of the refraction of light and the reason it occurs etc. but what is confusing me is the exact reason for the "slowing" and hence bending of light inside a transparent material. What are the exact properties that allow a transparent material to slow a beam...

    Refraction of light at air/water interface

    an insect hovers in a fixed position above the still water of a pond. draw a diagram to show approximately where it appears to be to a fish vertically below it. Okay I am confused between two things ... is it going to appear at a lower height than original or will be at the same height since...

    Calc Refractive Index of Cylinder w/Mirrored Surface

    A cylindrical material of radius R = 2.00 m has a mirrored surface on its right half, (as in figure that i have attached below). A light ray traveling in air is incident on the left side of the cylinder. If the incident light ray and exiting light ray are parallel and d = 2.00 m, determine the...
