Reflection of Waves | GCSE Physics Practice
Reflection occurs when a wave hits a boundary between two materials and bounces back.
Calculate the angle of reflection if the angle of incidence is 40°.
What is Reflection of Waves | Practice?
"The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated."
Which of these is an example of a longitudinal wave?
If an object absorbs more radiation than it emits, its temperature will ____.
Arrange these EM waves in order of INCREASING energy: Radio, Visible, UV, Gamma.
The distance between the same point on two adjacent waves is called the ____.
Law of Reflection
Law of Reflection: Angle of incidence = Angle of reflection.
Specular reflection: Smooth surface, clear image.
Diffuse reflection: Rough surface, scattered light.
Virtual Image: An image that light rays do not actually pass through (like a mirror).
Drawing Tip: Always draw the "Normal" line at 90 degrees to the surface. Angles are measured from the Normal, NOT the surface.
