A ray of light passes from air (n=1.00] into water (n=1.33) at an angle of incidence of 50°. What is the angle of refraction?

When a light ray travels from one medium, such as air, to another medium, such as glass or water, the speed of the light and the direction in which the ray is traveling changes. These changes are given by Snell's Law, c₁/c₂= sin θ₁/sinθ₂,where c₁ is

When a light ray travels from one medium, such as air, to another medium, such as glass or water, the speed of the light and the direction in which the ray is traveling changes. These changes are given by Snell's Law, c₁/c₂= sin θ₁/sinθ₂,where c₁ is the speed of light in the first medium, c₂ is the speed of light in the second medium, and θ₁ and θ₂ are the angles shown in the figure. Assume that c₁ is 3× 10⁸m/s (a) Find the speed of light in the second medium for θ₁= 43° and θ₂=33°. (b) Find the speed of light in the second medium for θ₁ = 35° and θ₂ = 21⁰. (a) For θ₁ = 43° and θ₂ = 33°, the speed of light in the second medium is _______m/s. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Do not round until the final answer. Then round to the nearest whole number as needed.) (b) For θ₁ = 35° and θ₂ = 21°, the speed of light in the second medium is_______m/s. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Do not round until the final answer. Then round to the nearest whole number as needed.)
