Joon puts on a pair of diffraction grating glasses that he bought in a novelty shop and looks at a mercury vapor street lamp that is 5.00 m away. He sees a yellow spectral line 1.16 m on either side of the light source. If the diffraction grating glasses have a slit separation of 2.49 X 10 m, what is the wavelength of the light Joon is observing? Radio station WLLH has two transmitters that sit atop nearby hillsides broadcasting a wave that is 214 m long. As Kiesha drives down the interstate parallel to the two transmitters at a distance of 1000. m, she hears an increase in signal from the station every 30.0 m. How far apart are the two transmitters
