In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ? Explain.
Size will be halved, intensity will be increased to four times.
Define a wavefront. Using Huygens’ principle, verify the laws of reflection at a plane surface.
In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ? Explain.
When a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the obstacle. Explain why
The refractive index of glass is 1.520 for red light and 1.525 for blue light. Let D1 and D2 be an of minimum deviation for red and blue light respectively in a prism of this glass. Then
A Young’s double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is
