AP EAMCET · PHYSICS · Electromagnetic Waves
Pick out the longest wavelength from the following types of radiations.
- A Visible blue light
- B Ultraviolet light
- C X-rays
- D Visible red light
Answer & Solution
Correct Answer
(D) Visible red light
Step-by-step Solution
Detailed explanation
Ultraviolet light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than \(\mathrm{X}\)-rays. \(\therefore \quad \lambda_{\text {red }} > \lambda_{\text {blue }} > \lambda_{\mathrm{UV}} > \lambda_{\mathrm{X} \text {-ray }}\) Hence,…
