What happens to a wave when it reflects against a fixed boundary? Comment on the direction of motion, and the orientation of the reflected wave (Is it upright or inverted after reflection)

What happens to a wave when it reflects against a free or loose boundary? Comment on the direction of motion, and the orientation of the reflected wave (Is it upright or inverted after reflection)

How does tension affect the speed of a wave? (As the tension in a string increases/decreases, the speed of a wave increases/decreases)

What is the effect of damping on the amplitude of a wave?

How does changing the frequency affect the speed of a wave?

When two pulses with a positive displacement meet at the same point, the resulting displacement of the string is (greater than/less than/the same as) the displacement of the original pulses.

When a positive and a negative pulse meet at a point, the resulting displacement is (greater than/less than/the same as) the displacement of one of the original pulses.
