Question

observe the graph

1. what is the amplitude of the wave?
2. what it it's wave length
3. what is the speed of the wave?
4. What is the frequency of the waves?

(Guys these are my last questions before submitting, and yes I'll follow those who answers )​

Answer 1

Answer:

1. Amplitude of the wave is 1.5 m

As amplitude is the maximum displacement of a particle from its mean position. Here, we can see the max displacement is 1.5 m

2. Wave length of the wave is 4m.

As, it is the length covered by one wave.

3. From A to G,

Time taken = 2s

Distance covered = 12m

Therefore,

Speed of the wave = distance/ time

= 12/ 2

= 6 m/ s

4. We know that,

f = v/ λ

Where, f = frequency

v = velocity

λ = wavelength

=> f = 6/ 4

=> f = 3/ 2

=> f = 1. 5 Hz
