How many images will be formed if the angle between the mirrors is 72 degree?
So, no of images = (360/ 72 )- 1= 5-1 = 4 images. Hence, the number of images = 4.
How many images are formed if the angle of 60 degree?
60 degeree=360/60 = 6-1=5 images.
How many images of an object will be formed if it is placed in front of the 2 mirrors placed at an angle of 60?
Two mirror inclined to each other produce five images of an object placed between them at a symmetrical position.
How many images are formed at 45 degrees?
| Angle between the two mirrors ( ) | Number of images formed (n) |
|---|---|
| 45 ° | 7 |
| 60 ° | 5 |
| 120 ° | 2 |
| 180 ° | 1 |
How many images will be formed if two mirrors?
Infinite images are formed when two plane mirrors are placed parallel to each other, irrespective of the distance.
How many images will be formed when you held the mirrors at 90?
three images
If you have a chance to look carefully at the images formed by right angle mirrors, then you will notice that right angle mirrors produce three images.
How many images will be formed if the angle between the mirror is 20 degree?
The number of images formed = (360/40), we get 9 images.
How many images will be formed if the mirror is arranged at 30?
∴ There will be 11 images formed when two mirrors are placed at an angle of 30°.
How many images are formed when two mirrors are placed at 90 degree?
Interestingly, a single mirror produces a single image; another single mirror produces a second image; but when you put the two single mirrors together at right angles, there are three images.
How multiple images are formed?
Multiple images are formed when two mirrors are placed at right angle to each other because when a ray incident on first mirror from an object it forms an image of the object. This process continues till no more reflection by either mirror is possible. This phenomenon is known as multiple reflection.
How many images are formed when the angle between two plane mirrors is more than 90 degrees?
Explanation: We get n = 360/90 – 1 = 3. When we simply use n = 360/90 we get an even number 4, but we should get a odd number so we use the other formula. So we get 3 images when two plane mirrors are placed at angle of 90⁰.
How many images can be seen at 72 degrees?
At 72° there can be 4 images or 5 images. There are 4 images if the object is placed symmetrically between the mirrors, as given by the formula. However, 5 images can be seen if the object is not placed symmetrically between the mirrors. This is always the case when 360/A is an odd number and the object is asymmetrically placed.
How do angles affect the number of images in a mirror?
As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images. If the image of an object is viewed in two plane mirrors that are inclined to each other more than one image is formed.
How many images does a 60 degree mirror have?
If A is the angle between the mirrors, the number of images is given by this formula: (360/A) -1. Therefore at 60° there are 5 images. At 72° there can be 4 images or 5 images. There are 4 images if the object is placed symmetrically between the mirrors, as given by the formula.
How many images are formed when two mirrors are kept together?
If two mirrors are kept at an angle theta then number of images formed by them will be of an object (360/theta-1) So no. Of images will be 360/72–1=4
