Question

Two wave pulses move toward each other along a rope.

Which diagram shows the resulting wave when they cross at point X?

Answer 1

The answer is B. It is the one that has the triangle pointing up on the topside of the rope and seems to be a bit bigger than the other triangles.

Step-by-step explanation:

Answer 2

The second option with a vertex pointing upwards.

Step-by-step explanation:

A wave is a disturbance that can be transmitted through a medium without causing a permanent displacement of the particles of the medium. The two types are; longitudinal and transverse.

In transverse wave, the direction of propagation of the wave is perpendicular to the direction of vibration of the particles of the medium. Examples are; water waves, light waves, X-ray etc. While in longitudinal waves, the direction of vibration of the particles is parallel to the direction of propagation of the waves. Examples are; waves in a slinky, waves in a rope, sound waves etc.

A wave in a rope is a form of longitudinal waves. When two wave pulses move toward each other, interference is observed.
