X-rays of wavelength, \(\lambda=r{A}\) have frequency :
- A \(3 \times 10^{14} Hz\)
- B \(1 \times 10^{15} Hz\)
- C \(3 \times 10^{16} Hz\)
- D \(3 \times 10^{18} Hz\)
Answer & Solution
Correct Answer
(D) \(3 \times 10^{18} Hz\)
Step-by-step Solution
Detailed explanation
\(f = c / \lambda\) \(f = (3 \times 10^8 \text{ m/s}) / (1 \times 10^{-10} \text{ m})\) \(f = 3 \times 10^{18} \text{ Hz}\)
