Light Refraction and Reflection Quiz Challenge!
How well do you know about light refraction and reflection?
Do you want to test your knowledge on light refraction and reflection? Let's see if you can answer this question:
If a light ray is refracted at an angle of 30 degrees as it passes from air into water, what is the angle of incidence?
Answer:
The answer is a) 48.6 degrees
When a light ray passes from air into water, it undergoes refraction due to the change in the speed of light between the two mediums. The angle of incidence is the angle between the incident ray and the normal (a line perpendicular to the surface of the water at the point of incidence).
By using Snell's Law, which states n1 * sin(theta1) = n2 * sin(theta2), where n1 and n2 are the refractive indices of the two mediums, we can calculate the angle of incidence to be approximately 48.6 degrees based on the given information of 30 degrees for the angle of refraction.
Understanding the principles of light refraction and reflection is essential in various optical phenomena and everyday applications. Keep exploring and learning more about the fascinating world of light!
