3) Please circle the correct answers, if there is no correct answer, then leave it blank(do not circle.) 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. 2. a) as the wavelength of the wave increases, the frequency increases, and the velocity decreases. b) as the wavelength of the wave increases, the...

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....

Determining Sample Uncertainty (Frequently this semester, we will skip this step to concentrate on other concepts in lab) For help: see How do I find the uncertainty in a measurement? Part 2: Sample Uncertainty 8. A student made the following nine measurements of the wavelength of a standing wave: 7= 14.4 cm, 15.1 cm, 14.2 cm, 14.6 cm, 14.4 cm, 14.8 cm, 13.7 cm, 13.9 cm, 14.9 cm. Assume the...

can you please help me with these 1. A wave has a period of 0.0002727343 seconds and a wavelength of 248.75 cm. What is the velocity of the wave in m/s? 2. The frequency stamped on a tuning fork is 230 Hz. The actual frequency you obtained through measurement is 232 Hz. What is the percent error of the stamped value? 3. What is the speed of sound in air under normal conditions in m/s? 4. A sound wave has...

E (t) = Eo cos (kz-wt) Where k is the wave-number and w is the angular frequency of the wave. Now some scientist tells you that a distant star has been observed to be green in color, with an observed frequency of fobserved 550 THz (terahertz, 1012). She also says that from other factors, it is known that the star should be emitting light with wavelength factual-1800 THz somewhere in the UV spectrum. They ask you to find two things...
