When a light ray strikes a smooth, flat surface, what is the relationship between the angle of incidence and the angle of reflection?

• They are equal.

• The angle of incidence is twice that of the angle of reflection.

• The angle of reflection is twice that of the angle of incidence.

• They combine to add up to 180^o.

Objects that generate their own light are called:

• luminous objects.

• illuminated objects.

• shiny objects.

• reflective objects.

Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. Which diagram below illustrates the law of reflection?

Electromagnetic energy travels in waves. When we describe electromagnetic waves, we often talk about the wave’s length and frequency. Which of these statements accurately describes the relationship between the wavelength and frequency of an electromagnetic wave?

• If wavelength increases, frequency increases.
• If frequency decreases, wavelength increases.
• If frequency remains constant, wavelength increases.
• If wavelength remains constant, frequency increases.
