Question

One sine wave has a period of 2ms.Another has a period of 5ms, and other has a period of 10ms.Which sine wave is changing at a faster rate

Answer 1

Answer:

2ms

Explanation:

According to the graph it can be proved

Answer 2

Answer:

The wave having a time period of 2ms wave is changing at a faster rate.

Explanation:

First, let's see the following relation.

$T\propto\frac{1}{f}$        (1)

Where,

T=time period of the wave

f=frequency of the wave

∴ From equation (1) we can say that the wave with a lesser time period is changing at a faster rate as its frequency will be higher.

So, from the question we have,

T₁=2ms

T₂=5ms

T₃=10ms

By comparing the values of T₁, T₂, and T₃ we can say that the wave having a time period of 2ms wave is changing at a faster rate.
