Question

For a pulse moving in a heavy string the junctions of the string behaves as a

• A. perfectly rigid end
• B. free end
• C. partially rigid end
• D. rigid end

Answer 1

The correct option is A perfectly rigid end

Waves in a heavy string move slower compared to thinner strings. And the junction acts as a perfectly rigid end because of the change in the density and also the lesser speed of the wave.
