Product description
1. In a liquid with a refractive index 1.7 placed point light source. At what maximum distance should be placed over the source disk of radius 1 cm, the light did not come out of the liquid in the air?
Given:
n = 1,7
R = 1 cm = 10-2 m
Search:
H =?
2. How many times will change the distance between the first and second interference fringes on the screen, if the wavelength of two coherent linear light sources change with 5105 see 6,5105 to see?

Additional information
3. When the device for observation of Newton's rings were immersed in liquid, the diameter of the eighth dark rings decreased from 2.92 mm to 2.48 mm. What is the refractive index of liquid and the wavelength in the air, if the radius of curvature of the lens is 0.5 m?
4. Between point source of light with a wavelength and the screen is orifice diameter d. Derive the formula for calculating the radius of Fresnel zones fit into this hole. The distance from the source to the aperture is equal to x, and from the diaphragm to the screen Y.
5. What is the Brewster angle of the light beam upon reflection from the water surface (nin = 1.33) from the bottom (from the water)? Find the angle of total internal reflection and reflection at Brewster's angle of the beam incident on the top surface of the water from the air.
