Refraction of Light

Physics ⇒ Light and Optics

Refraction of Light starts at 8 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Refraction of Light. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
A ray of light passes from water (n=1.33) to glass (n=1.5). Will the ray bend towards or away from the normal?
Describe what happens to a ray of light as it passes from air into glass at an angle.
Explain why a coin placed at the bottom of a glass of water appears to be raised.
Explain why a swimming pool looks shallower than it actually is.
A fish in a pond appears to be at a different position than it actually is. This is due to _______.

A fish in a pond appears to be at a different position than it actually is. This is due to _______.
A pencil appears bent when placed in a glass of water. This is due to _______.
The angle between the incident ray and the normal is called the _______.
The apparent depth of a swimming pool is _______ than its real depth due to refraction.
The bending of light as it passes through the atmosphere causes stars to appear to twinkle. Is this due to refraction?
True or False: Refraction can cause objects under water to appear closer to the surface than they really are.
True or False: Refraction can occur with sound waves as well as light waves.
True or False: Refraction only occurs when light enters a denser medium.
