Answer to Problem 1CQ

Solution: 4 antinodes

Explanation of Solution

Given:

A standing wave oscillating on a string at frequency f0.

Formula used:

f=nv/2l

Where f is the natural frequency

n is the no. of antinodes

v is the velocity of wave

l is the length of the string

Let m-value be n then:

From the figure we can see that there 4 anti-nodes.

To determine

(b)

How many antinodes will there be if the frequency is doubled to 2f0

Answer to Problem 1CQ

Solution:

8 antinodes

Explanation of Solution

Calculation:

Suppose L be the length of the string.

L=nλ/2

We have n = 4,

so:

λ=L/2

Let f0 be the frequency.

v=f0λ = f0×L/2 = f0L/2

When frequency is doubled then f0 becomes 2 f0:

Using f=nv/2l, we get:

2 f0 = nv/2L=(n×f0×L)/(2×2×L)

From above calculation we will get:

n = 8

Conclusion:

Using the f=nv/2l, number of nodes and antinodes can be calculated when other things are provided.
