Question 195 out of 5 pointsThe Doppler effect causes the spectrum of an approachinglight source to be shifted toward which end of the spectrum? Answers: a. blue b. red c. There is insufficient information to answer the question. d. Neither. The colors do not shift at all, because the speed of light is constant. Response Feedback: The speed of light is constant, but color does vary depending on speed of approach or recession. The correct answer is blue, because the wave crests of light from an approaching light source are bunched closer together, making the wavelength shorter. Remember, blue light has shorter wavelengths than red light.
Question 20Needs GradingProvide the symbol used for the speed of light, and explain why that particular symbol is used for the speed of light. Response Feedback: [None Given] Question 213 out of 3 pointsThe speed of a wave is calculated by multiplying its frequency (number of waves per second) by ________ . (one word only, all lower case letters) Question 22Needs GradingGenesis 1:1 says "In the beginning, God created the heavens and the earth." Genesis 1:3 says "Then God said, 'Let there be light,' and there was light."Genesis 1:14-16 says, in part, "Then God said, 'Let there be lights in the expanse of the heavens ...,' ... and God made the two great lights...he made the stars also."(1) Discuss whether there was physical light in the heavens as of God's first having created the heavens, verse 1:1. (2) Then, explain the nature of the light in verse 1:3. Be sure to FIRST answer both parts, (1) and (2).
