are composed of ionized gas trapped in a magnetic arch rising above the surface of the Sun. When seen along the edge of the Sun, they appear pink in color. However, when seen against the Sun's bright surface they appear as dark.

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

If frequency goes down, what happens to wavelength? does it get shorter or longer?
