• ### Optics Prism Question?

Consider an equilateral prism made from crown glass with an index of refraction for red light of 1.509 and an index of refraction for blue light of1.517.White light is incident on the prism at 37°. After emerging from the prism, the light is projected onto a viewing screen parallel to the exit side of the prism. Draw a sketch of the situation and describe mathematically what is seen on the viewing screen.

I don't need the sketch, ive already made one, but I am unsure of how to describe it mathematically

• ### Triple integral set up?

Set up an integral which represents the integral of f(x, y, z) = z over the region below

the top hemisphere of radius 3 and above the triangular region in the xy-plane bounded

by x = 1, y = 0, and x = y You need not evaluate the integral.

• ### Physics Optics Question?

Shown below is a thin-lens combination in air. Consider an object 30 cm to the left of the front doublet(i.e. lens made by putting two lenses together in contact with each other...though all you need for this problem is their effective focal length). Compute the image location and magnification. f1= 30 cm f2=-20 cm

• ### Physics Optics Question?

a. Determine the focal length of a thin planar-convex lens in air, having a radius of curvature with a magnitude of 50.0mm and a refractive index of 1.50. (Hint: think carefully about what the radius of curvature for the planar side is).b. What, if anything, would happen to the focal length if the lens were placed in a tank of water?

• ### Physics reference frame question?

An observer in an inertial reference frame experiences two events simultaneously at positions x1=2.5 km and x2 = 6.8 km. A second observer in an inertial reference frame moving with 𝛽=0.62 in the +x direction relative to the first observer, experiences the same two events. What (a) distance between the events and (b) time interval between the events does the second observer measure?

• ### Relative Muon Decay question?

A group of students uses an aircraft to do the muon lifetime experiment. They use their muon counter to count 115,000 muons moving toward the ground at a speed of 0.985c, at an altitude of 6,200 meters in a particular time interval. How many muons would you expect them to count on the ground in the same time interval with the muon counter (a) if the decay followed classical transformations; (b) with the correct relativistic transformations? (you can ignore collisions of the muons with air molecules)

• ### Physics mass-energy imbalance question!?

The reaction 4He + 4He + 4He →12C (three helium atoms fuse resulting in a carbon atom) is more important to you than you probably know. It’s a primary reaction by which stars produce carbon and you happen to be a carbon-based lifeform! Assume the helium nuclei are at rest and calculate the mass-energy imbalance (the energy released by the reaction).

• ### Physic Optics Question!?

A thin film of magnesium fluoride is deposited onto a piece of glass. Refractive indices for the film and glass are 1.38 and 1.52, respectively. Assume that the film is non-absorbing. For monochromatic light incident normally on the film, determine:(a) the reflectance and transmittance from the air-film surface, and(b) the reflectance and transmittance from the film-glass surface.(c) Now assume that the film is removed. Calculate the reflectance and transmittance from the air-glass surface (without the film).

• ### Relativity Physics help!?

Hey, remember that physics student from the first week of class? They designed an accelerator for electrons using classical physics. The intent was to accelerate the electrons to the speed of light with a constant, uniform electric field of 1000 Volts/meter. Using classical physics our blissfully unaware student determined that a 256 meter long accelerator would achieve the goal. a) What value of β does the student's design actually achieve? b)The student needs a grade of B on their design and their instructor assigns numerical values of grades with numerical values of β. How long does the accelerator need to be for the student to get a grade of 85% (beta=0.85β = 0.85)?
