Energy of a photon of violet color is:
Correct answer: A. Greater than that of red color
- A. Greater than that of red color
- B. Less than that of red color
- C. The same as that of red color
- D. None of these
Explanation
Violet light has a higher frequency (shorter wavelength) than red; since E = h f, the photon energy for violet > red.

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.
