Select the ways in which you can induce current in a wire. Select all that apply.
□ Connect a wire to a voltage source
□ Move the wire through a magnetic field
□ Coiling the wire around a permanent magnet
□ Leave the wire put in the sun

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:

photocells convert light energy to electricity

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
