What is diffraction of light?
Describe what happens to the single slit diffraction pattern when the width of the slit is less than the wave length of the wave.
What are the characteristic elements associated with a diffraction grating? How is plane transmission grating constructed?
What is the fundamental physical difference between interference and diffraction? Explain with figures.
Radio waves diffract around buildings but not light waves, why?
Why can we readily observe diffraction effects for sound waves but not for light?
The diffraction of sound waves is more evident in daily experience than that of light waves. Why?
Light waves undergo diffraction around an edge. Can sound wave diffract around an edge? Explain.
Why is diffraction of sound waves easier to observe than that of light waves?
Distinguish between Fresnel diffraction and Fraunhofer diffraction.
What are difference between interference and diffraction?
Suppose a monochromatic light of wavelength 'X' is incident normally on a narrow slit of width 'd' and focused on a screen. Derive condition for the first minimum of intensity on the screen in terms of wavelength λ and angle of diffraction 'θ'.
