Chapter 14.5

Mastering Waves in Two Dimensions

Dive into the fascinating world of 2D waves! Understand reflection, refraction, and diffraction through interactive demonstrations. Gain valuable insights applicable to physics and engineering.


What You'll Learn

Identify reflection, refraction, and diffraction behaviors of two-dimensional waves
Apply the law of reflection to calculate angles of incidence and reflection
Explain how waves change speed and wavelength when refracting between deep and shallow water
Recognize that frequency remains constant during reflection and refraction
Describe how gap size affects the degree of circular spreading in wave diffraction

What You'll Practice

1

Calculating angles of reflection using the law of reflection

2

Drawing and analyzing wave diagrams showing refraction between media

3

Determining wavelength and speed changes from deep to shallow water

4
