The process of transfer of heat in fluids by actual movement of particles is called

A. Evaporation

B. Convection

C. Radiation

D. Conduction

View Answer & Solution Discuss

Correct Answer: Option B

Explanation:
Convection requires medium, movement of hot and cold masses. Land/sea breeze, trade winds, heating water. Conduction vibration transfer without particle movement.

The eye defect 'astigmatism' is corrected using

A. Cylindrical lens

B. Concave lens

C. Convex lens

D. Bifocal lens

View Answer & Solution Discuss

Correct Answer: Option A

Explanation:
Astigmatism: cornea curvature not spherical, different focal lengths in different planes. Corrected by cylindrical lens which has different powers in perpendicular axes. Not simple spherical lens.

Question #3 Report Error

Prism dispersion occurs because:

A. Total internal reflection

B. Different colors have different frequencies

C. Prism absorbs colors selectively

D. Refractive index depends on wavelength

View Answer & Solution Discuss

Correct Answer: Option D

Explanation:
Dispersion: n varies with λ (Cauchy's law), causing different refraction angles for colors. Frequency constant across media; wavelength changes. Memory aid: 'n(λ) ⇒ v(λ) ⇒ different bending; violet bends most'. Conceptual question testing dispersion mechanism, frequently examined in competitive optics sections.
