what are the effects of refraction give some examples
Answers
Explanation:
1. Bending of light.
a. If light is moving from rarer to denser medium then it moves towards the normal.
b. If it is moving from denser to rarer medium then it moves away from the normal.
2. Change in wavelength of light.
a. rarer to denser — wavelength decreases
b. denser to rarer — wavelength increases
3. Spliting of light ray if it is polychromatic in nature.
a. like white light which on refraction splits up into 7 primary colors upon refraction because different colors have different speeds in different medium other than air or vaccum.
No changes are seen in frequency of light.
Answer:
Effects of refraction of light
An object appears to be raised when paced under water. Pool of water appears less deep than it actually is. If a lemon is kept in a glass of water it appears to be bigger when viewed from the sides of glass. It is due to refraction of light that stars appear to twinkle at night.
