When the mirrors are inclined at 90 degree we get which images?
Therefore, 8 images will be formed.
How many images will be formed if two plane mirrors are placed at an angle of 40?
When two mirrors are placed at an angle of A , number of images formed are 360oA−1 . As ∠A=40o , number of images will be 360o40o−1=9−1=8 .
How many images will be formed if two plane mirrors are placed at an angle of 30 degree to each other?
∴ There will be 11 images formed when two mirrors are placed at an angle of 30°.
How many images are formed by two plane mirrors inclined at 60?
60 degeree=360/60 = 6-1=5 images.
How many images are formed when 3 mirrors are placed at 90?
The number of images formed is n = 360/90 – 1 = 3.
How many images will be formed if two plane mirrors are placed at 60?
How many images are formed when 2 plane mirrors are kept at an angle of 30ᵒ and 60ᵒ respectively to each other?
| Angle between the two mirrors ( ) | Number of images formed (n) |
|---|---|
| 45 ° | 7 |
| 60 ° | 5 |
| 120 ° | 2 |
| 180 ° | 1 |
How many images are formed by plane mirrors at an angle?
The formula for the number of images formed by plane mirrors at an angle of θ° is (360°/θ) – 1 . If two mirrors are inclined at an angle x and this value of x is submultiple of 180° then number of images formed is n = (360/x)-1
What is the angle between two mirrors?
The angle between two mirrors is 90 degrees. What is the number of images formed? The angle between two mirrors is 90 degrees. What is the number of images formed?
How many images can be drawn from a 72 degree mirror?
Let (theta) be angle between two mirrors then if 360/ (theta) is odd then number of images will be=360/ (theta). For (theta)= 72 degree this ratio is 5, so number of images is 5. If the above ratio is even ,then number of images will be= [ (360/theta)-1].
How do you calculate the number of images in a mirror?
The formula for calculating is the number of images is [math]\\frac{360}{\heta} – 1[/math] where [math]\heta[/math] is the angle between two mirrors in degrees. Hence 3 images form if you replace the angle in degrees.
