A) polarized
B) of longer wavelength
C) of shorter wavelength
D) of high intensity
Correct Answer: C
Solution :
The laser beam being narrow, intense, parallel monochromatic and highly coherent is used to determine the position of object. Energy of ray \[\Omega \], where h is Plancks constant, c is speed of light, \[\Omega \] is wavelength. Hence, shorter the wavelength, more the intense energy of beam. Hence, maximum accuracy is achieved.
