You see a flash of lightning strike a clock tower during a thunderstorm. you count 3 s between when the lightning flashes and when you hear thunder with a sound level of 60 db. what is the sound level of the thunder for someone standing only 10 m from the clock tower?

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

c. newton's third law of motion

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
