1)An object is placed 72 cm away from a glass surface of a container having water. At what point will the object appear from the glass?
2)What is the fractional change in wavelength of light when it passes through water from glass?

Sorry, Mik
Refractive index of glass is 3/2 and that of water is 4/3

I won't bother about Homework comments. This is not homework. It's an assignment where the teach said that we can get help from anywhere except our classmates.

How can this be answered without knowing the index of refraction of the media? Light will slow down in water and glass compared to air / vacuum, but #1 doesn't state whether the observation is made from air or in water to glass to water.

It is the bending of light as it passes through another material because it slows down. However, if it strikes an object at 90 degree or a curved surface it will not refract.

Do your own homework.
