ANSWER:Solution 6P
Portions of electromagnetic waves A, B, and C are represented below (not drawn to scale):
Step 1
Here we have to rank them in order of
(a) increasing frequency
Frequency is defined as the number of cycles the wave undergoes per second. From the above diagram it has been found that, the number of cycle in A is more and in C is least.
Thus the order of increasing frequency is,
C < B < A
