Answer 2

Step-by-step explanation:

_________________

Given ,

• Focal length = 0.5 m

Find ,

• Radius of curvature = ?

Solution :-

Radius of curvature = 2 × focal length

• 2 × 0.5 m

We know that,

• 1 m = 100 cm
• 2 × 5/10 × 100
• 10/10 × 100
• 1 × 100
• 100 cm

:. Radius of curvature is 100 cm.
