The frequency of light ray having the wavelength 3000Å is
Options
(a) 9×10¹³ cycle/sec
(b) 10¹⁵ cycle/sec
(c) 90 cycle/sec
(d) 3000 cycle/sec
Correct Answer:
10¹⁵ cycle/sec
Explanation:
n = v / λ = 3 × 10⁸ / 3000 × 10⁻¹° = 10¹⁵ cycle/sec.

(c) 90 cycle/sec
(d) 3000 cycle/sec
10¹⁵ cycle/sec
n = v / λ = 3 × 10⁸ / 3000 × 10⁻¹° = 10¹⁵ cycle/sec.
