A child has a near point at 10 cm10 \text{ cm}. Determine the maximum angular magnification the child can obtain using a convex lens of focal length 10 cm10 \text{ cm}.

Options

  1. A1010
  2. B0.50.5
  3. C11
  4. D22

Correct answer

D. 22

Step-by-step solution

The maximum angular magnification of a simple microscope is obtained when the final image is formed at the near point of the eye.

The formula for maximum angular magnification is given by:

m=1+Dfm = 1 + \dfrac{D}{f}

where DD is the near point distance and ff is the focal length of the convex lens.

Given:

D=10 cmD = 10 \text{ cm}

f=10 cmf = 10 \text{ cm}

Substituting the values into the formula:

m=1+1010m = 1 + \dfrac{10}{10}

m=1+1=2m = 1 + 1 = 2
