In the spectrum of white light by a prism, the colour at the extreme end opposite to the base of prism is: (a) violet (b) yellow (c) red (d) blue
Ans : 2 The colour of the extreme end opposite to the base of the prism is red.
Hint: The angle of deviation decreases with the increase in wavelength of light for a given angle of incidence. Since the red light has greatest wavelength, it gets deviated the least and is seen on the extreme end opposite to the base of prism.
