magnifying glass
rainbow
radio
mirror

1. use the space below to draw diagrams of the waves behaviors

behavior	example

|reflection|
|refraction|
|diffraction|
absorbtion|
|resonance|

1. how is the angle of incidence related to the angle of reflection when a wave bounces off an object during reflection?

Explanation:

Step1: Match wave behaviors to examples

1. Reflection: Light bounces off a mirror, so Mirror is the example.
2. Refraction: A magnifying glass bends light (refracts) to magnify, so Magnifying Glass is the example.
3. Diffraction: Radio waves bend around obstacles to reach receivers, so Radio is the example.
4. Absorption: A rainbow forms when light is absorbed, reflected, and refracted by water droplets; this is linked to selective absorption of wavelengths.
5. Resonance: (A common example for resonance could be a musical instrument, but for the given images, if we extend, or note that a rainbow also involves resonance in light interactions, but more accurately, a typical example is a vibrating tuning fork, but for the scope, we can align appropriately. However, for the given images, we use the logical matches first, then for the last, a standard example.)

Step2: Answer reflection angle question

The law of reflection states the relationship between the two angles.

Answer:

For Question 3:

• Magnifying Glass: Refraction
• Rainbow: Refraction (and dispersion, linked to refraction/absorption)
• Radio: Diffraction
• Mirror: Reflection

For Question 4 (Table Completion):

Behavior	Example
Refraction	Magnifying Glass
Diffraction	Radio
Absorption	Rainbow (selective wavelength absorption)
Resonance	(Example: A vibrating tuning fork, or a speaker vibrating at natural frequency)

For Question 5:

According to the law of reflection, the angle of incidence is equal to the angle of reflection, measured relative to the normal (a line perpendicular to the surface the wave bounces off of).
