Consider the following statement about visible light, UV light and X-rays: 1. The wavelength of visible light is more than that of Xrays. 2. The energy of X-ray photons is higher than that of UV light photons. 3. The energy of UV light photons is less than that of visible light photons. Which of the statements given above is/are correct?
Options
- A1,2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
Correct answer
B. 1 and 2 only
Step-by-step solution
Only statements, the wavelength of visible light is more than that of X-rays and the energy of X-ray photons is higher than that of UV light photons is correct. While the energy of UV light photons is greater than that of visible light photons and not less than as mentioned in the statement 3
