Does the magnifying power of a microscope depend on the colour of the light used? Justify your answer. |
|
Answer» tion:✔ A microscope consists of two lenses and we know focal length of a lens depends on the refractive index of the lens which itself depends on the wavelength or COLOUR of the light used.✔ HENCE, if colour of light changes focal length of the lens also changes which would simultaneously change the IMAGE distance.✔ This change in image distance will change the MAGNIFYING power (as magnifying power is the ratio of image distance to object distance).✔ Therefore, we can say the magnifying power of a microscope depends on the colour of the light used. |
