We are looking down at a film at 90 deg, and a shining orange light with a wavelength(vacuum) of 710 nm is on the film. It has a refractive index of n = 1.32, and is surrounded by air.

A) draw out a diagram with refractive indices of the surfaces

B) What is the minimum thickness of the film for it to look bright due to reflected light?

Pls show steps and whatever else you can show to understand the question, thanks!

Expert Solution

2nt = (2k–1)λ/2 now for minimum thickness k=1, t=λ4n=710nm4×1.32=1.34μm ans.

Orange light of 600 nm and violet of 360 nm are illuminating the thin film of index of refraction 1.2, which is surrounded by air. Next several questions will be about this particular film. 1. The minimum thickness of the film providing maximum reflection for both these wavelengths is equal to Group of answer choices three quarters of wavelength of orange light in the film five quarters of wavelength of orange light in the film three quarters of wavelength of...

We are shining a red light on a totally different metal, and are ejecting photo electrons with a small KE of 1.5 eV. We are going to make predictions about what happens when we shine light of a greater intensity red light on the same sample. Identify what classical (wave) theory of light incorrectly predicts we would observe. Contrast that with the result which the Quantum Model correctly predicts. I am looking for several solid details.

A photoelectric experiment was performed by separately shining a laser at 450 nm (blue light) and a laser at 560 nm (yellow light) on a clean metal surface and measuring the number and kinetic energy of the ejected electrons. Which light would generate more electrons? Which light would eject electrons with greater kinetic energy? Assume that the same number of photons is delivered to the metal surface by each laser and that the frequencies of the laser lights exceed the...

The Photoelectric Effect Lab 10 Prelab Questions : Predictions If the light shining on the metal becomes brighter, will the kinetic energy of the emitted electrons increase? If the light shining on the metal becomes brighter, will the number of electrons being emitted per second (the photo-current) increase? If the frequency of the light shining on the metal is increased, will the number of electrons being emitted per second (the photo-current) increase? If the frequency of the light shining on...

1) The light shining on a diffraction grating has a wavelength of 477 nm (in vacuum). The grating produces a second-order bright fringe whose position is defined by an angle of 9.71°. How many lines per centimeter does the grating have? 2) The wavelength of the laser beam used in a compact disc player is 566 nm. Suppose that a diffraction grating produces first-order tracking beams that are 1.1 mm apart at a distance of 3.1 mm from the grating....

A thin film is in the air with a wavelength of 615 nm and is 90 nm thick. What is the minimum index of refraction? The light at wavelegth= 410 nm is a first order maximum at 12 degrees. What is the angle for the second order maximum at 670 nm? The central light is 3 m away when every other slit is covered; how far will the first interference max be? All but 2 adjacent slits of 10 are...
