Place two plane mirrors at an angle of 90° to each other. Place a small object between them. Images will be formed in both mirrors. How many images do you see? Try this Now change the angle between the mirrors as given in the following table and count the number of images each time. How is this number related to the measure of the angle? Discuss this relationship. Angle Number of images 120 11.3 Mirrors at right angles to euch other 90 360 - 1 А n = number of images, A= angle between the mirror 45 30 htnined for different values of angles is
Answers
Answer:
three
Explanation:
Let, the angle is x
If the value of 360/x is even, then we will use the formula
no. of images= 360/x -1
If the value of 360/x is odd, then we use the formula
no. of images= 360/x
Now, in this question, let us first find value 360/x
so, 360/90 = 4 , where 4 is an even number.
so we will use the formula 360/x - 1
so, 360/90 -1 =4–1 = 3
so the image formed will be three
Answer:
There is a formula for such questions.
Let, the angle is x
If the value of 360/x is even, then we will use the formula
no. of images= 360/x -1
If the value of 360/x is odd, then we use the formula
no. of images= 360/x
Now, in this question, let us first find value 360/x
so, 360/90 = 4 , where 4 is an even number.
so we will use the formula 360/x - 1
so, 360/90 -1 =4–1 = 3
so the image formed will be three
