Two waves of the same intensity produce interference. If intensity at the maximum is 4I, then intensity at the minimum will be:
Correct answer: A. 0
- A. 0
- B. 2I
- C. 3I
- D. 4I
Explanation
When two waves of the same intensity interfere destructively, they cancel each other out completely, resulting in zero intensity at the minimum point. This is why the correct answer is 0. The other options are incorrect because they do not consider the nature of destructive interference.

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.

The ratio of intensities between point A and that of the central fringe is 0.853. The path difference between the two waves at point A will be:
A double-slit experiment is immersed in a liquid with a refractive index of 1.33. The separation between the slits is 1.0 mm and the distance between the slit and screen is 1.33 m. If slits are illuminated by a parallel beam of light whose wavelength is 6300 Å, then the fringe width will be:
Interference fringes from sodium light (1 = 5890 Å) in a double slit experiment have an angular width of 0.20o. To increase the fringe width by 10%, the wavelength of light used should be:
Light of wavelength λ is incident on a slit. The first minima of the diffraction pattern is found to lie at a distance of 6 mm from the central maximum on a screen placed at a distance of 2 m from the slit. If the slit width is 0.2 mm, then the wavelength of the light used will be:
The figure shows a double-slit experiment. P and Q are the slits. The path lengths PX and QX are nλ and (n+2)λ respectively, where n is a whole number and λ is the wavelength. Taking the central fringe as zero, what is formed at X:
Plane polarised light is passed through a polaroid. On viewing through the polaroid, we find that when the polaroid is given one complete rotation about the direction of the light, one of the following is observed :
