4. Calculating frequency and Wavelength of electromagnetic radiation
V=(f)(λ)
All the waves move at speed of light(3.0 E 8)
Example:

5. How is the brightness of a light affected by distance?
the area that the light illuminate gets wider the further it is from the source, the wider that area the dimmer the light will seem because it is still the same amount of light but in a bigger area.

6. Distinguish between specular and diffuse reflections of light
Reflection off of smooth surfaces such as mirrors or a calm body of water leads to a type of reflection known as specular reflection
Reflection off of rough surfaces such as clothing, paper, and the asphalt roadway leads to a type of reflection known as diffuse reflection

7. Applying the law of reflection for a flat mirror
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.

8. Nature of images formed by flat mirrors
The plane mirror will produce an image of the object on the opposite side of the mirror. The distance from the object to the mirror equals the distance from the image to the mirror.

9. Equations for concave and convex mirrors
(1/f)= (1/do) +(1/di)
M= (hi/ho) = (-di/do)
Ex. 2.7m tall object produces a real image 1.1 m tall. What is the magnification?
M= (-1.1) / (2.7) = -.41

12. Real and virtual images
Real images- When a real image is formed, it still appears to an observer as though light is diverging from the real image location. Only in the case of a real image, light is actually passing through the image location.
Virtual images- For plane mirrors, virtual images are formed. Light does not actually pass through the virtual image location; it only appears to an observer as though the light is emanating from the virtual image location.
