Question

A rope is vibrating so as to form the standing wave pattern shown. How many antinodes are present in the rope?a- 5b- 4c- 8d- 10e- 3

Answer 1

Based on the wave pattern provided, the number of antinodes is 8, and the correct answer is option c.

In the standing wave pattern depicted, the points of maximum displacement or oscillation are called antinodes.

These occur at the ends of the rope and at points where the amplitude is maximum.

To determine the number of antinodes, we need to count these points.

Looking at the given options:

a- 5

b- 4

c- 8

d- 10

e- 3

Firstly, let's analyze the image.

A standing wave typically forms a pattern with alternating nodes and antinodes.

Nodes are points of minimal or zero displacement, while antinodes have maximum displacement.

In the given options, we can count the antinodes by identifying the points of maximum amplitude.

Each peak and trough can be considered as an antinode.

By visually inspecting the pattern, we can determine the number of antinodes.

After careful examination, the correct answer appears to be option c- 8. This implies that there are 8 points of maximum displacement along the rope.

In conclusion, based on the wave pattern provided, the number of antinodes is 8, and the correct answer is option c.

Answer 2

c) 8

Step-by-step explanation

When you shake a rope, the particles in the rope move up and down, and the wave moves forward or away from the source of energy. The rope moves in a direction that is perpendicular

Nodes are the places where the rope doesn't move at all; antinodes occur where the motion is greatest.

Step 1

let's check the graph:

a) Nodes

and Antinodes

so, in the ripe there are 8 antinodes

therefore, the answer is

c) 8
