(MEDAL+FAN+COOKIE_HUG! YASSS) 8. Short Answer. A communication satellite transmits a radio wave at frequency of 5x10^9 Hz. What is the signal's wavelength? Assume the wave travels in a vacuum. Show your work. (3 points)
Give me a minute
Oki ^_^
C (speed of light) = 3.0x10^8 m/s = wavelength * frequency. In waves problems, frequency is inversely proportional to wavelength. If the frequency of the radiowave (transverse wave) is 5.0x10^9 3.0x10^8 = 5.0x10^9 * wavelength (3.0x10^8/5.0x10^9) = Wavelength = 0.06 meters
can I ask another question?
Go ahead.......
19. Both gamma rays and X-rays are used to see inside the body. Which one is used to make images of bones? how are the other rays used?
X-ray is used to make images of bones. Bones are very dense with Calcium nuclei which makes them very visible on the x-ray films. Gamma ray = it would kill you. Not specifically should on the applications of gamma rays. Probably in nuclear chemistry, with nuclear fission and decay.
wow, thank you! ^_^ you're really smart♥
Thanks, and goodluck on your endeavors.
