[QUOTE="Oneablegal, post: 4655951, member: 499451"] [h2]Homework Statement [/h2] Light of wavelength 600 nm in air enters a piece of glass. The speed of light in this glass is 0.650 times the speed in air. Calculate the angle of refraction, Given that the angle of incidence of this light ray is 40°. [h2]Homework Equations[/h2] Snell's Law Sin(θ1)/sin(θ2) = v1/v2 [h2]The Attempt at a Solution[/h2] I calculated the wavelength to be 390 nm. (600nm x 0.65). I know the Speed of light in glass is less than an air so light is going to slow down and bend towards the normal, therefore the angle of refraction will be less then the incident 40°. I know the practice problem answer is 24.7 degrees. I need help bridging the gap, so to understand this problem. Please help! Thank you in advance. [/QUOTE]
