```Electromagnetic Waves and Optics Review Questions:
1.
Calculate the range of frequencies in the electromagnetic spectrum that correspond to visible
radiation. The range of wavelengths is 400 nanometers to 700 nanometers (0.0000004 m to 0.0000007
m).

Find the position of the image of the object shown by tracing at least two light rays that leave the object
hit the reflecting or refraction surface and enter your eyes. Indicate whether the image is virtual or real.
When determining the path of the light rays, be sure to use the normal as a reference.

materials. Trace their paths as they cross the boundary (or boundaries).
