Light of wavelenght 436nm in air enters a fishbowl filled with water, then exits through the crown-glass wall of the container. Find the wavelengh of the light in the water and in the glass.

Wavelength in a medium = (Wavelength in vacuum)/(Index of the medium)
So...
Wavelength in water = 436 nm / 1.33
Wavelength in glass = 436 nm / 1.5

I can't promise this is right!!
I'm pretty sure u have the equations but just in case u don't
frequency=speed of light / wavelength..f=3*10^8/(436*10^-9)..
U should have the index number of glass and water. u find the speed of light in water and glass by deviding 3*10^8 by the index number of each...now u have the frequency from the first part and the speed of light in water and glass and now by using the equation f=c/wavelength u find the new wavelength..I hope this helps..the only part i am not sure about is if the index of water and glass affects the frequency,,,good luck
