- D. 30-T 42 Find the critical angle of the glass prism.When a liquid is introduced into the air space between the lens and the plate in a Newton's-rings apparatus, the diameter of the tenth ring changes from 1.56 cm to 1.04 cm. Find the index of refraction of the liquid. Need Help? Read It Watch ItWhen a wide beam of parallel light enters water at an angle,the beam broadens. Explain.
- is a flashlight an example of a concave or convex lens ?The 3 pink arrows equal the dark purple one. Please use the picture to help me solve the question. ThanksA particular material has an index of refraction of 3.50 what percent of the speed of light in vacuum is the speed of light in the material
- Give refraction rule for a diverging Lens.The index of refraction for violet light in silica flint glass is 1.66 and that for red light is 1.62. What is the angular dispersion of visible light passing through an equilateral prism of apex angle 60.0° if the angle of incidence is 46.0°? (See figure. The index of refraction for air is 1.00.)Can you please help find the apex angle of the prism?
