When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
A ray of light traveling from air to water is incident at an angle of 64 degrees Part of the light is reflected at an angle of what?
It is reflected at exactly the same angle, but on the other side of the normal at the point of incidence.
A diver shines light up to the surface of a smooth pond at a 10 degree angle some light passes into the air above and the part that reflects back into the water makes an angle of how many degrees?
10
When a light ray passing from air into water at an angle of 30 degrees from the normal air what angle would it make?
When a light ray passes from air into water at an angle of 30 degrees from the normal, it undergoes refraction. The angle of refraction can be calculated using Snell's Law, which states n1sin(theta1) = n2sin(theta2), where n1 and n2 are the refractive indices of air and water, respectively, and theta1 and theta2 are the angles of incidence and refraction. Given that the refractive index of air is approximately 1 and water is approximately 1.33, the angle of refraction can be calculated to be approximately 22.6 degrees using Snell's Law.
What describes the angle between water level and the incline of a water ski ramp?
An acute angle
