Question

An object is placed at distance of 50cm from concave mirror of focal length 16cm find the image distance​

Answer 1

Explanation:

from concave mirror of focal length 16cm find the image distance

Answer 2

Answer:

23.52 cm

Explanation:

Given:

Object distance: 50cm

Focal length : 16cm

Solution:

We can simply find answer to this question using the simple mirror formula.

Now we know from given that,

Object distance(do): 50cm

Focal length (f): 16cm

Image distance(dI):?

1m=100cm.

Now using the mirror formula we try using the formula for a concave mirror

1/f=1/do+1/dI1/f=1/do+1/dI

Inserting values into the equation

1/f=1/do+1/dI1/f=1/do+1/dI

1/16=1/50+1/dI1/dI

1/16-1/50=1/dI1/dI

50-16/(16*50)=1/dIdI

34/800=1/dIdI

dIdI =800/34

dIdI =23.52 cm

Hence image distance will be 23.52cm
