When a light ray passes through a small opening, the longer wavelength of the red color as compared to the shorter wavelength of the violet color will:
Correct answer: D. Diffract more
- A. Reflect less
- B. Diffract less
- C. Reflect more
- D. Diffract more
Explanation
When a light ray passes through a small opening, it undergoes a phenomenon known as diffraction. Diffraction occurs when a wave encounters an obstacle or passes through a narrow aperture, causing it to bend or spread out. The extent of diffraction depends on the wavelength of the light. In this case, the longer wavelength of the red color compared to the shorter wavelength of the violet color means that the red light will diffract more than the violet light. This is because longer wavelengths tend to diffract or spread out more than shorter wavelengths when passing through a small opening.

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.
