A He-Ne laser beam with an intensity of 1.00 103 W/m2 is incident from air to ice, perpendicular to the surface of the ice. Find the intensity of the beam transmitted into the ice.
Problem 3 (25 points) A silicon photodetector has an internal photo responsivity of 0.5 A/Wt wavelength of 850 nm. When photons of wavelength 850 nm are incident normally on this photodetector, some photons are reflected back and some photons penetrate to the detection region and are absorbed by the photodetector. (a) The index of refraction of silicon is 3.45. If the electric current measured by this photodetector is 20 mA, what is the incident optical power? (b) Silicon has a...

A beam of light is incident upon a material whose dispersion coefficient is dn/dλ =-10.7 10-5 nm-1, with no = 1.500 when λο = 527.0 nm. If θ denotes the refraction angle, what is the absolute value of the angular separation Δθ of the refracted beams produced by this material if the incident beam contains wavelengths between = 467.0 nm and 2617.0 nm and the beam's angle of incidence i is 25.95*? A beam of initially unpolarized light passes through...
Question 3 (7 pts): You shine a laser of intensity 2000 W/m² onto a reflective solar sail in a vacuum. If the solar sail has an area of 10 m2 and a mass of 100 kg, how long will it take to go from rest to 1000 m/s? Assume that the force from the light is the only force acting on the solar sail.
A 0.5 m thick sample of um thick sample of In is illuminated with monochromatic light of hv=1.5 eV. The absorption coefficient 104 cm 1. The power incident on the sample is 15 mW.

Theory section is below for the equations
PRELAB Read the theory section below. Calculate the photon wavelength in nm corresponding to a photon energy equal to the theoretical band gap energy of S1.121 eV and GaAs, 1.422 eV. These will be used to set the monochromator. THEORY One of the most important characteristics of a semiconductor is its band gap energy Eg Whereas an electron in an isolated atom has discrete energy levels, an electron in a semiconductor crystal has...
