Question #1 Report Error

A ray of light passes from air to glass (refractive index 1.5). If angle of incidence is 30°, angle of refraction is (sin30=0.5)

A. 45°

B. 30°

C. 19.47°

D. 60°

View Answer & Solution Discuss

Correct Answer: Option C

Explanation:
Snell's law: n₁ sin i = n₂ sin r. 1×0.5 = 1.5 sin r => sin r = 0.5/1.5 = 1/3 ≈ 0.3333 => r ≈ 19.47°. So A.

Alpha particle is:

A. Photon

B. Electron

C. Neutron

D. Helium nucleus

View Answer & Solution Discuss

Correct Answer: Option D

Explanation:
Alpha (α) radiation: helium nucleus (²He⁴, 2p+2n), +2 charge, low penetration. Beta: electrons; Gamma: photons; Neutron: neutral particle. Memory aid: 'Alpha = He nucleus; Beta = electron; Gamma = EM wave'. Radioactivity classification frequently tested in competitive exams to distinguish radiation types.
