Question
A thermal insulator is a material that _____.
never reaches thermal equilibrium with objects in contact with it
quickly reaches thermal equilibrium with objects in contact with it
allows the passage of heat
resists the passage of heat
A ray in glass arrives at the glass-water interface at an angle of 48° with the normal. The refracted ray, in water, makes a 61° angle with the normal. The index of refraction of water is 1.33. Then the ray in glass is redirected so its new angle of incidence is 25°. What is the angle of refraction in the water?
