Cards in this deck (4)
- 1What is the relationship between the angle of incidence and the angle of reflection? A. The angle of incidence is bigger B. The angle of reflection is bigger C. The angles are the sameC. The angles are the same
The law of reflection requires that two rays are at identical angels but on opposite sides of the normal which is an imaginary line at right angles to the mirror where the rays meet. This law is called Snell's law! - 2Use the law of reflection and the embedded protractor in order to draw the reflected ray associated with the given incident ray for the following plane mirror situations. (Markings are provided at 15° increments.) A. 1 B. 2 C. 3B. 2
The angle of incidence (the incoming angle) always equals the angle of reflection (outgoing angle)
This is called Snell's law
- 3Use the law of reflection and the embedded protractor in order to draw the reflected ray associated with the given incident ray for the following plane mirror situations. (Markings are provided at 15° increments.) A. 1 B. 2 C. 3A. 1
The angle of incidence (the incoming angle) always equals the angle of reflection (outgoing angle)
This is called Snell's law
- 4We call the reflection from a smooth, mirror-like surface SPECULAR REFLECTION. When the surface of water is wind-blown and irregular, the rays of light are reflected in many directions. This means the outgoing rays are reflected at many different angles and the image is disrupted. Reflection from such a rough surface is called DIFFUSE REFLECTION and appears matte. What word would you use to describe the reflection being used for the laser maze? A. Diffuse reflection B. Specular reflection C. Mirrored ReflectionB. Specular reflection
The mirror's surface is smooth and will give a clear reflection
