Question

calculate the solid angle subtended by the periphery of an area of 1 cm^2 get up at the point situated symmetrically at a distance of 5 cm from the area

Answer 1

Hi friend,

Solid angle is the ratio of the area and the square of the distance of area from the point.

So, here the solid angle is,
Ω=Area/d2=1/5²
⇒Ω=0.04 steradians

HOPE THIS HELPS YOU:-))

Answer 2

The solid angle is 0.04 steradians.

Given:

Area = 1 $m^2$

D = 5 cm

Solution:

Solid angle is the ratio of the area and the square of the distance of area from the point.

So, here the solid angle is,

$\Omega=\frac{\text {Area}}{d^{2}}$

By simply substituting the values of the area and the distance we can calculate the solid angle.

$\Omega=\frac{1}{5^{2}}$

$\Rightarrow \Omega=0.04 \ \text{steradians}$

This is how we can calculate the solid angle. The unit of solid angle is Steradians.
