the focal length of a concave mirror is 15cm. The radium of curvature is​

Answer 1

Answer:

The focal length of a concave mirror is 15cm.

The radius of curvature= 2*15

=30 cm.

Answer 2

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large{\sf{\underline{\underline\red{Solution!!}}}}$

$\green\longrightarrow\:\:\sf{R = 2f}$

$\green\longrightarrow\:\:\sf{F = 15\:cm}$

We have to find the radium of curvature,

So,

$\pink\longrightarrow\:\:\sf{R=2 \times 15 }$

$\pink\longrightarrow\:\:\sf{R=30\:cm }$

$\therefore$  The radium of curvature = 30 cm.
