The distance between the objective and eyepiece lenses in a microscope is 19 cm . the objective lens has a focal length of 5.5 mm. what eyepiece focal length will give the microscope an overall angular magnification of 200?

The focal length of eyepiece is 3.68 cm.

Explanation:

Given that,

Distance = 19 cm

Focal length = 5.5 mm

Magnification = 200

Object distance = -25 cm

We need to calculate the focal length

Using formula of magnification

Put the value into the formula

Hence, The focal length of eyepiece is 3.68 cm.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
