Q3508.General ScienceAsked in: CDS · CDS-II 2025, GKEasy

Twinkling of a star is due to :

  1. A.Interference of light
  2. B.Refraction of light
  3. C.Polarization of light
  4. D.Diffraction of light
Show answer
Correct answer: B. Refraction of light

Starlight is bent again and again by layers of air of changing density, so its path and brightness keep shifting and the star seems to twinkle.

Q3509.General ScienceAsked in: CDS · CDS-I 2026, GKMedium

An object is placed at a distance of 15 cm in front of a concave mirror with a radius of curvature of 20 cm. Which one among the following statements is correct for the image formed?

  1. A.The image is 30 cm from the mirror on the same side as the object.
  2. B.The image is formed at a distance of 30 cm behind the mirror.
  3. C.The image is 60 cm from the mirror on the same side as the object.
  4. D.The image is formed at a distance of 60 cm behind the mirror.
Show answer
Correct answer: A. The image is 30 cm from the mirror on the same side as the object.

The focal length is 10 cm, and an object between F and C of a concave mirror gives a real image beyond C, in front of the mirror.

  1. A.Jet Stream
  2. B.Geostrophic Wind
  3. C.Westerlies
  4. D.Easterlies
Show answer
Correct answer: B. Geostrophic Wind

A geostrophic wind blows high above the surface, where the pressure gradient force and the Coriolis force balance and the air flows parallel to the isobars.
