Light moves from flint glass (n = 1.66) into water at an angle of incidence of 26.0°.
a) What is the angle of refraction?
Answer in units of

Explanation:

Through Snell's Law, we can solve this.

The formula is:

n1 = flint = 1.66

n2 = water = 1.33

theta1 = 26.0°

theta2 = angle of refraction

Substituting these values in the formula,

Therefore, the angle of refraction is 33.17°

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
