Question

The twinkling of star is due to:

• A. reflection
• B. dispersion
• C. absorption
• D. refraction

Answer 1

Answer:

D. refraction

• Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.
• Rainbows, atmospheric refraction, distortion of underwater objects, telescopes, and prisms are all examples of refraction
• This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows
