Question

number of images formed by a mirror on an angle of 60 dgree​

Answer 1

Answer:

There are two main complexity measures of the efficiency of an algorithm: ... "Time" can mean the number of memory accesses performed, the number of comparisons between integers, the number of times some inner loop is executed, or some other natural unit related to the amount of real time the algorithm will take.

Answer 2

Explanation:

If the image of an object is viewed in two plane mirrors that are inclined to each other more than one image is formed. The number of images depends on the angle between the two mirrors.

The number of images formed in two plane mirrors inclined at an angle A to each other is given by the formula below for the different cases:

Case(1) : If (360/A) =Even then,

Number of images =(360/A)−1

Case(2) : If (360/A) =Odd,

(1) If mirrors are placed symmetrically then,

Number of images =(360/A)−1

(2) If mirrors are placed unsymmetrically then,

Number of images =(360/A)

Here, angle of inclination =60

0

So, (360/A) =(360/60)=6 [Which is even]

Hence, The no. of images will be =(360/A)−1

Substituting A as 60

0

in the formula (360/60)−1=6−1=5

Hence, the no. of images formed will be 5.

So, option(B):5 will be the correct answer.
