Question

from the given graph find the time period and frequency for a and b​

Answer 1

Answer:

for. A. 1sec. ;1hz

for B. 0.5sec;2hz

Answer 2

Answer:

For A, Time period = 1 sec and frequency =1Hz

For B, Time period = 0.5 sec and frequency =2Hz

Explanation:

In the graph for the wave A,

It completes 1 complete oscillation at point x which takes 1 sec as mentioned in the graph.

∴ Time period = 1 sec

and Frequency = $\frac{1}{T}$ = $\frac{1}{1}$ = 1Hz.

In the graph for the wave B,

It completes 1 complete oscillation at point y which takes 0.5 sec as mentioned in the graph.

∴ Time period = 0.5 sec

and Frequency = $\frac{1}{T}$ = $\frac{1}{0.5}$ = 2Hz.

Hope it helps! :-)
