Answer

To calculate the magnification produced by the lens, we will use the formula:

ext{magnification} = rac{ ext{image height}}{ ext{object height}}
  1. Identify the values for image height and object height.

    • Let's assume that we have an image height of 10 cm and an object height of 5 cm (these values should be obtained from context or given data).
  2. Substitute the values into the equation:

    ext{magnification} = rac{10 ext{ cm}}{5 ext{ cm}} = 2
Thus,themagnificationproducedbythelensis2. Thus, the magnification produced by the lens is 2.

Step 2

Answer

As the object is moved further away from the lens, the size of the image will decrease. This is because as distance increases, the image produced by the lens also tends to become smaller.
