Question

The distance between the position of an object placed in front of the mirror and its image in the mirror is 15cm. Find the distance of the object from the mirror.

Answer 1

Given:

• Distance between the position of an object placed infront of mirror & it's image = 15 cm

To find:

• Distance between object and the mirror

Solution:

As we know that

Distance b/w the image & mirror = 2V

Where

• V is velocity or the distance . As per the question it is the distance = ?

Now , substituting the value of v

→ 15 = 2(v)

→ v = 15/2

→ Distance b/w the image & the mirror = 7.5cm

Hence , distance between the image and the mirror = 7.5cm

★ Knowledge enhancer

μ = c/v or v1/v2

μ = Real depth / Apparent depth

Light enters medium a, crosses medium b and then leaves from medium c, then ^aμ_c = ^aμ_b x ^bμ_c

Here , ^ indicates power & _ indicates base

Answer 2

Given:-

The distance between the position of an object placed in front of the mirror and its image in the mirror is 15cm$.$

To find:-

Find the distance of the object from the mirror.

STEP BY STEP EXPLANATION:-

☢️ FOR FINDING THE DISTANCE BETWEEN

♻️ OBJECT AND IMAGE IN THIS FORMULA

Formula = 2 v

V stands for velocity , distance

( Will be based on given condition )

♻️ Hence, putting the value of the formula

♻️ 2 v

➡️ 2* 15 cm

➡️ 30 cm

♻️ Hence, the answer is 30 cm
