If you have a green light bulk, its temperature is between which two lights?arrow_forward( Why? From fireworks to stars, the color of light is useful in finding out what's in matter. The emission of g by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms. Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be identified by heating or burning the materials and examining the color(s) of light given off in the form of bright-line spectra.

Matter can transmit, absorb, and reflect light. Visible light includes a range of colors and is the only part of the electromagnetic spectrum that we can see. Read the scenario about light and answer the questions in complete sentences. You have a blue backpack and you look at it through blue glass. What color would the backpack appear to be? Suppose you took the same blue backpack and looked at it through red glass, what color would the backpack appear to be? Explain your answers.arrow_forward

Opaque objects block/absorb light), and Reflection/scattering What are the main/basic definitions and differences of these in reference to interactions of light with matter? My professor had given an example using a picture that had a house, a man standing in it with furniture, snow outside, a tree, and the sun. He pointed out the different colors and how they related to these terms but he was very quick and I don't feel like I understand how each of these things can be distinguished.arrow_forward
