When a beam of light is used to determine the position of an object, the maximum accuracy is achieved if the light is

Options

Apolarised
Bof longer wavelength
Cof shorter wavelength
Dof high intensity.

Correct answer

C. of shorter wavelength

Step-by-step solution

For maximum accuracy in finding the position of an object using a light beam is achieved, when the light beam used is of shorter wavelength, because if the wavelength is longer, the spread in the wave will be more.
