The speed of sound in air at 0°C is 331 m/s. At 22°C, approximately

A. 350 m/s

B. 331 m/s

C. 343 m/s

D. 360 m/s

Answer: Option C

Solution (By JKSSB Mock Tests)

v ≈ 331 + 0.6×T(°C) = 331 + 0.6×22 = 331+13.2 = 344.2 m/s, nearest 343 m/s.

Correct Answer: Option A

Explanation:
Rainbow: sunlight enters raindrop (refraction + dispersion), reflects internally (TIR), exits with further refraction. Primary rainbow: one TIR; secondary: two TIRs. Memory tip: 'Rainbow = refraction + dispersion + TIR in water droplets'. Application question testing atmospheric optics, frequently appearing in competitive exams.

Correct Answer: Option C

Explanation:
While Faraday performed the groundbreaking experimental work discovering electromagnetic induction, it was James Clerk Maxwell who formalized these discoveries mathematically. Maxwell's equations (a set of four differential equations) elegantly united electricity, magnetism, and optics, proving theoretically that light itself is a propagating electromagnetic wave.
