The number of images between two plane mirror inclined at an angle θ when the object is placed symmetrically between the mirrors is given as
n=(360o/ θ) −1
Given,
θ=60o
∴n=(360o/60)−1=6−1=5
n=(360o/ θ) −1
Given,
θ=60o
∴n=(360o/60)−1=6−1=5

(360/A)-1
=(360/60)-1
6-1=5
therefore the answer is 5(a)

If an object is placed unsymmetrically between two plane mirrors, incl...
Explanation:
When an object is placed between two plane mirrors inclined at an angle, multiple images are formed due to the reflection of light. Let's analyze this situation step by step:
1. Initial Reflection:
- The object is placed between the two mirrors.
- The first reflection occurs on one of the mirrors, let's say Mirror 1.
- The image formed due to this reflection will be virtual and located behind Mirror 1.
2. Reflection between Mirrors:
- The light from the virtual image formed by Mirror 1 reaches Mirror 2.
- The second reflection occurs on Mirror 2.
- The light reflects back towards Mirror 1.
- The third reflection occurs on Mirror 1.
- This process continues back and forth between the two mirrors.
3. Number of Reflections:
- Each reflection between the mirrors forms a new image.
- The total number of images formed can be calculated by considering the number of reflections between the mirrors.
In this case, the angle between the mirrors is 600. Let's denote the angle of incidence and the angle of reflection as i and r respectively.
- The angle of incidence is equal to the angle of reflection (i = r) for each reflection.
- The sum of the angles of incidence and reflection is equal to the angle between the mirrors (i + r = 600).
4. Calculation:
- For each reflection, the angle of incidence and reflection will be half of the angle between the mirrors (i = r = 300).
- The total number of reflections can be calculated by dividing the angle between the mirrors by the sum of the angles of incidence and reflection (600 / 300 = 2).
- Therefore, a total of 2 reflections occur between the mirrors.
5. Total Number of Images:
- Including the initial reflection on Mirror 1, the total number of images formed will be the number of reflections plus 1 (2 + 1 = 3).
- However, we also need to consider the initial object itself as an image.
- Therefore, the total number of images formed is 3 + 1 = 4.
Conclusion:
- In this situation, when an object is placed unsymmetrically between two plane mirrors inclined at an angle of 600, a total of 4 images are formed. Thus, the correct answer is option 'B' (4).
