Hi,
My Question:
A beam of light is emitted in a pool from a depth of 62.0 cm. Where must it strike the air-water interface, relative to the spot directy abovie, in order that the light does not exit the water?
My Work
Tan(49)=(x/62.0cm), got 49 degrees from the textbook where it says that it won't reflect at this angle.
x=Tan(49)62.0 cm
x= 71.3 cm
Is this right??
Thank You
