Lesson 11. Energy transfer in waves. Interference

Students should be able to:

Visualize wave fronts of plane waves, circular waves and spherical waves.
know that waves transport energy but not matter.
Calculate the intensity of a wave in a given distance from the source and relate the solution to the power of the source.
Calculate the phase difference and the path difference between two interfering waves.
Calculate the amplitude of the interference of two waves at specific points.

Warmup your students! Ask two activating questions at the beginning and at the end of the lesson
