The larger a wavelength is, the ______ the frequency of the wave.
What is lower frequency.
This line must be found before the angles of incidence and reflection can be measured.
What is the Normal line.
The lens of an eye is the same as this type of curved lens.
What is a convex lens.
This source of light comes from chemical reactions that occur within a living organism
What is bioluminescence.
If the angle of incidence is 60 degrees, what was the angle of the incident ray?
What is 30 degrees.
