The first diffraction minima due to a single slit diffraction is at

\theta = 30^\circ

for a light of wavelength

5000\,\,\mathop \mathrm{A}\limits^ \circ

. The width of the slit is

View answer and explanation

Correct option: B

1.0 \times {10^{ - 4}}cm

Option B (

1.0 \times {10^{ - 4}}cm

) is correct because it is calculated using the formula for the first diffraction minima in single-slit diffraction.

reach a point in opposite phase. The resultant amplitude is H-polaroid is prepared by Evidence for the wave nature of light cannot be obtained from Which radiation in sunlight, causes heating effect In the propagation of light waves, the angle between the direction of vibration and plane of polarization is In Young’s experiment, one slit is covered with a blue filter and the other (slit) with a yellow filter. Then the interference pattern
