Question

A student sets up a slinky on a smooth tabletop in the manner shown here.




How can he produce transverse waves in the slinky by moving its free end Q?
(1) at an angle of 45º with the table top
(2) backward and forward along the length of the slinky
(3) up and down
(4) left and right

Answer 1

In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. The student can generate a transverse wave by moving the free end Q of the slinky, vertically up and down.

Hence, the correct answer is option 3.
