Interference

After we have watched the video, answer the following questions.

Q1) What are the types of waves that form at a boundary between 2 different mediums?

The wave that passes the boundary is called _____

The speed and the wavelength of the _________ is the same as the speed and the wavelength of the _________.

The _______________ (in the denser medium) is traveling slower than the ______________ (in the less dense medium).

The ___________ (in the denser medium) has a smaller wavelength than the _____________ (in the less dense medium).

What if the travelling wave couldn’t pass through the second medium (fixed end), what would happen?

What are the types of Interference?

When we have a superposition of waves with an equal but opposite displacement, this is called ____________

The point N in the first panel is called _________ and it happens because the pulses cancel each other. (zero displacement)

A waves in superposition with an equal magnitude and their displacement are in the same direction, this is called ____________

The point A in the second panel where the amplitude of the two waves meet, is greater than individual waves is called __________
