Question

the figure given below shows an incident pulse P reflected from a rigid support.
which out of A. B. C and D represent the reflected pulse correctly .






please reply it fast. I really need this

Answer 1

Answer:

The correct option is C

Explanation:

• When an incident pulse is reflected, the wave becomes inverted after bouncing off the surface
• If a wave is in the positive y-axis, after reflection it becomes in the negative y-axis
• Other wave characteristics such as amplitude, time period, and energy do not change
• The net result of the incident and reflected pulse should be zero
• A pulse with a downward displacement will reflect as one with an upward displacement
• In the given diagram, the incident pulse has an upward displacement so the reflected pulse must have a downward displacement.
