Question

The Solid Angle (\[\Omega\]) is mathematically defined by which formula?

Options

• Ω = \[\frac {A}{r}\]

• Ω = \[\frac {A}{r^2}\]

• Ω = \[\frac {V}{r^3}\]

• Ω = \[\frac {s}{r}\]

Answer 1

Ω = \[\frac {A}{r^2}\]

Explanation:

The Solid Angle as the ratio of the intercepted surface area to the square of the radius.
