Name the radiations of wavelength shorter than 4 × 10−7 m.
Suppose a monochromatic X-ray beam of wavelength 100 pm is sent through a Young's double slit and the interference pattern is observed on a photographic plate placed 40 cm away from the slit. What should be the separation between the slits so that the successive maxima on the screen are separated by a distance of 0.1 mm?
How will you investigate the existence of the radiation beyond the red and violet extremes of the spectrum?
