What happens when a red colored cloth is exposed to red light?
Correct answer: B. Reflect
- A. Transmit
- B. Reflect
- C. Refract
- D. Absorb
Explanation
When a red colored cloth is exposed to red light, the cloth will reflect the red light. This is because the pigments in the red cloth absorb all other wavelengths of visible light except the red wavelengths, which are then reflected back.The other options are not correct in this scenario:a) Transmit - The red light would not be transmitted through the cloth.c) Refract - Refraction occurs when light passes through a medium with a different refractive index, which is not the case here.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
