Maximum diffraction takes place in a given slit for

Options

A. infrared light
B. radio waves
C. `gamma` rays
D. ultravolet light

Explanation

One will be tempted to discuss the equation `mlambda=asintheta` for minimum intensity or a similar equation for maximum . However it must be noted that no single spectrometer or a slit or grating will be useful for all the regions extending from `gamma` rays to radio waves . One can only compare close wavelengths for a given method . If the question had been , among the four , which one has maximum wavelength , one would have given that `gamma` is in the order `gamma` rays , ultraviolet , infra - red and radio waves. Radio waves have maximum wavelength . This question cannot be answered.
