Question

describe the nature of the image formed when the object is placed at a distance of 30 cm from a concave mirror of lenght 15 cm. Draw ray diagram for same. please answer this i will return you 10 thanks​

Answer 1

Answer:

v = -30cm

Explanation:

focal length(f) = - 15cm

u = -30cm

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u} \\\\\frac{1}{v} = \frac{1}{f} - \frac{1}{u} \\\\\frac{1}{v} = \frac{1}{(-15)} - \frac{1}{(-30)} \\\\\frac{1}{v} = \frac{-2 - (-1)}{30} \\\\\frac{1}{v} = \frac{-2 + 1}{30} \\\\\frac{1}{v} = \frac{-1}{30} \\\\v = -30$

Here you go,

for ray diagram

Answer 2

Answer:

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex or concave. Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
