Question

What is the total magnification of a refracting telescope having an objective and eyepiece lens of focal lengths 30.0 cm and 0.40 cm respectively?

Answer 1

The total magnification of a refracting telescope is -75

Step-by-step explanation:

f₀ = 30 cm

`f_(e)` = 0.40 cm

Magnification in telescope => m = - f₀ /
`f_(e)`

m = - 30 / 0.040

m = -75

Magnification in telescope = -75

The negative sign shows the image is inverted
