3) Please circle the correct answers, if there is no correct answer, then leave it blank(do not circle 1. a) red light has a smaller wavelength and lower frequency than blue light. b) red light has a longer wavelength and higher frequency than blue light. 2. Since sound travels at about 340 m/s in air, we can see that a) electromagnetic waves travel at the same speed as sound. b) electromagnetic waves travel slower than sound if air is present....

1.
a) the velocity of electromagnetic waves increases with the
frequency of the wave.
b) the velocity of visible light waves is the same, however
other types of electromagnetic waves has different velocities
depending on the frequency.

I would appreciate if you could check my work for #2 and help
me out with #3. I tend to get confused with proportions, and I’m
not quite sure how to relate tension to frequency and wavelength
(unless that is the idea, and one doesn’t affect the other).
Thanks so much!
