Assume that a heavy rope is tied to a light rope. Imagine a transverse wave that propagates from the light rope onto the heavy rope. For this wave, which of the following will occur?

(i) The frequency will decrease.
(ii) The frequency will increase.
(iii) The wave speed will increase.
(iv) The wave speed will decrease.

1.(iii) only.
2.(ii) and (iii) only.
3.(i) and (iv).
4.(iv) only.

Question 2

Consider a rope hung from the top of a tall ceiling to the ground. Someone sets up waves from the bottom of the rope and watches as they propagate up the rope. The wave's speed along the vertical rope will
1.remain constant up the rope.
2.increase with vertical position up the rope.
3.decrease with vertical position up the rope.
4.increase until midway up the rope, then decrease.
