For a Young's Double Slit Experiment, white light is used for observing interference patterns. Find the wavelengths that are missing from the pattern and are directly in front of one of the slits.  Correct Answer Both 1 and 2

Content:

Young's Double-slit experiment is a simple demonstration of the wave nature of light. It experimentally verifies that just like waves interfere, light also interferes and forms interference fringes. The setup of Young's double-slit experiment consists of two coherent sources(in form of slits) separated by a small distance 'd'. A screen is placed at a distance 'D' from the point slits to observe fringes. The path difference between the light rays from the two slits introduces a phase difference. This phase difference leads to the formation of interference fringes.

                              Additional Information

When Young's Double Slit Experiment is performed using white light the following observations are made:

  1. The central fringe will be white
  2. The fringe closest on either side of the central white fringe is red and the farthest will appear violet. After few fringes, no clear fringe pattern is seen.

Consider the following statements in case of Young’s double slit experiment. a) A slit S is necessary if we use an ordinary extended source of light. b) A slit S is not needed if we use an ordinary but well collimated beam of light. c) A slit S is not needed if we use a spatially coherent source of light Which of the above statements are correct?
In a Young’s double slit experiment, the distance between the two slits is 0.5 mm and the distance between the screen and the slits is 1 m. When a light of wavelength 500 nm is incident on the slits, what would be distance between the two second bright fringes?
The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
