Homework Statement
hello i have a question i really don't get how to solve
a laserlight with the wavelength of 630 goes from air to glas of water with the angle of incidence = 40 degrees. The glass is 10 cm
I have to calculate how much the light has been displaced in the water when it goes out to the air again after the 10 cm
please i ned a step by step on how to solve it
I have solved that the angle of refraction is 28,9 degrees
Homework Equations
I have put a photo of it so u can see what i mean,
The Attempt at a Solution
all the numbers in photo there i have calculated so maybe they arent right but i did it as good as I am able to...they ask me how much will the light be displaced when it gets back to air again (and to be honest i don't get the question too well but i guess it is something about how it will be when it goes out to the air from the bottom of the glass)
