What are the different waves that make up the electromagnetic spectrum? (lowest to highest energy) | radio waves, microwaves, infrared waves, Uv light, x-rays, gamma rays |
Long Wavelength equals what kind of frequency? | Low Frequency |
Short Wavelenth equals what kind of frequency? | High Freq. |
What are the colors of the electromagnetic spectrum? | ROY G BIV |
What are the three different types of materials that affect light differently? | Opaque(blocks light), Transparent(transmits light easily), and Translucent(transmits some light) |
What is the difference between AC(alternating current) and DC(direct current)? | In direct current, electrons flow in the same direction. In alternating current, electrons constantly change direction at a regular rate. |
What is static electricity? | buildup of electrical charges in an object |
What are some physical properties? | Color, shape, hardness, mass, volume, weight, and density. |
What is the difference between a mixture and a pure substance? | A mixture is two or more substances that have been physically combined. A pure substance is just one substance, no combonations. |
