The figure below contains information collected about different objects in space and the types of radiation detected from each of these objects. How does the information included in this figure show that technology is important in science?
Technology allows scientists to detect information in space beyond what’s visible to the human eye
Technology allows scientists to capture planetary images but not images in other remote locations such as the depths of the oceans
Jenna used various pieces of fruit in an experiment to test the sweetness of the fruit. She then began to wonder how each fruit gets its color. She started by researching why an apple is green.
An apple is green because it refracts green color
An apple is green because it absorbs all colors of visible light but reflect green light.
