Question

Statement-1: if white light is used in YDSE, then the central bright fringe will be white.

Statement-2: In case of white light used in YDSE all the wavelengths produce their zero order maxima at the same position.

A. Statement-1 is true, statement-2 is true: Statement-2 is a correct explanation for statement-1
B. Statement-2 is true, statement-2 is true: statement-2 is not a correct explanation for statement-1
C. Statement-1 is true, Statement-2 is false.
D. Statement-1 is false, Statement-2 is true.

Answer 1

In Young's Double Slit Experiment, the central bright fringe appears white when white light is used. However, different wavelengths of light produce their zero order maxima at different positions, resulting in the dispersion of colors in higher-order maxima.

Step-by-step explanation:

Statement-1: The central maximum will be white but the higher-order maxima will disperse into a rainbow of colors.
Statement-2: The lower wavelength components of light will have less diffraction compared to higher wavelength components for all maxima except the central one.

From the given statements, Statement-1 is true. When white light is used in Young's Double Slit Experiment (YDSE), the central bright fringe will appear white. However, Statement-2 is false. In the case of white light used in YDSE, all the wavelengths do not produce their zero order maxima at the same position. Different wavelengths of light have different angles of diffraction, resulting in the dispersion of colors in higher-order maxima.

Therefore, the correct answer is Option C: Statement-1 is true, Statement-2 is false.
