Here is a figure that shows a light ray that is H=23cm parallel
to and above the ground.
The light ray goes through a medium with an index of refraction
of n1=1.2, and some of it reflects and some of it
refracts.
The refracting part goes into a medium with an index of
refraction of n2=1.5.
If the angle ? = 30 degrees:
What is the distance between point A and point B (in
cm)?
What is the angle between...
Q2) Figure 1 shows the photon flux Ф of a light source having a cross-section area 3cm2. The light source has operated just for two seconds to illuminate a semiconductor material (its area is 2cm2 and band gapE). a) b) c) d) How many photons has the light source emitted? How many electrons could be generated in the semiconductor material? How many photons can be absorbed by the semiconductor material? Calculate the power density H of the light source at...

Screen 84 GO In Figure 35-50, two isotropic point sources S, and S, emit light in phase at wavelength 1 and at the same amplitude. The sources are separated by distance d = 6.001 on an x axis. A viewing screen is at distance D = 20.0, from S, and par- -d-to- allel to the y axis. The figure shows two rays reaching point P on the screen, at height yp. (a) At what value of yp do the rays...
A monochromatic light ray enters a glass sphere of radius 5 cm from air as shown in the figure. The incident ray is parallel to the diameter AOB with a separation of h = 4 cm. After entering the glass sphere, the ray crosses the diameter AOB at a certain point between center O and point B.mainly ask (d) and (e)(d) If incident light is unpolarized, is the reflected light at point P perfectly polarized? If not, find another separation...
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,...
The figure below shows a ball of mass m=1.5 kg which is
connected to a string of length L=1.4 m and moves in a vertical
circle. Only gravity and the tension in the string act on the ball.
If the velocity of the ball at point A is v0=8.6 m/s,
what is the tension T in the string when the ball reaches the point
D?
The figure below shows a ball of mass m=1.5 kg which is connected to a...

Gravitation Exercises Problem 1 Consider the following figure. An illustration shows two particles, each labeled M, one placed at each end of a vertical line. A horizontal line intersects the vertical line right at its center. A point P is at the right end of this horizontal line. The distance between the vertical line and the point P is r. The distance between the horizontal line and each particle M is a (a) Compute the vector gravitational field at a...
