Many amateur astronomers start out with a 4-inch (aperture) telescope and then graduate to a 16-inch telescope. By what factor does the light-gathering power of the telescope increase with that upgrade

Respuesta :

Answer:

16 / 4 = ratio of diameters

A = pi r^2

A16 / A4 = pi * 8^2 / (pi 2^2) = 16

The light gathering power would increase by a factor of 16

The light-gathering power of the telescope increase by 16 times with that upgrade

What is Light gathering power of telescope ?

The Light gathering power  of an optical telescope is the ability of a telescope to collect a lot more light than human eye .

Light gathering power can be calculated by the ratio of their diameter squared

light gathering power with initial aperture = L1

light gathering power with final aperture = L2

L2 / L1 = [tex]16^{2}[/tex] / [tex]4^{2}[/tex]

L2/L1 = 16

L2 = 16 L1

The light-gathering power of the telescope increase by 16 times with that upgrade
