Stars do not all have the same temperature. The color of light emitted by stars is characteristic of the light emitted by hot objects. Telescopic photos of three stars are shown below: (i) the Sun, which is classified as a yellow star, (ii) Rigel, in the constellation Orion, which is classified as a blue-white star, and (iii) Betelgeuse, also in Orion, which is classified as a red star. (a) Place these three stars in order of increasing temperature. (i) sun (ii) Rigel (iii) Betelguese

Hey everyone where ask determine which light will make the environment relatively warmer for the plant. We're told that at around 610-720 nm we have our red light And at around 400 - nm, we have our violet blue light. Now to answer this question, we need to recognize that as we move to the right, our wavelength is increasing and we also know that as we move to the left, our energy is increasing. Now. To answer this question, we know that hotter objects typically have a higher average kinetic energy. And since we recall this, this must mean that our violet blue light will make the environment relatively warmer for our plan. And the reason why is because we have a higher energy from our violet blue light. So I hope that made sense. And let us know if you have any questions.
