Unit 6- Waves
Waves and Electromagnetic Energy
| Question | Answer |
|---|---|
| The number of waves that pass a point in one second; also determines the pitch of a sound wave | frequency |
| The distance between two crests, two troughs or one crest and one trough | wavelength |
| Height of a wave; also determines how loud a sound is | amplitude |
| the highest point of a wave | crest |
| the lowest point of a wave | trough |
| A form of energy that travels through space in waves and does not need a medium; is organized by wavelength and frequency | electromagnetic energy |
| Electromagnetic waves with the longest wavelengths and lowest frequencies | radio waves |
| Electromagnetic waves with the shortest wavelength and highest frequencies | gamma waves |
| A part of the electromagnetic spectrum that has less energy than visible light; it is the radiation that heat gives off | infrared radiation |
| The only electromagnetic energy waves we can see. Light we can see. | visible light |
| An acronym for red, orange, yellow, green, blue, indigo, and violet | ROYGBIV |
| Light from the sun. can be dangerous to humans and causes sunburn | ultraviolet radiation |
| Electromagnetic radiation having a very short wavelength; is used to make images of teeth and bones and in airport security | x-ray radiation |
| a property of light energy; light waves bouncing off of surfaces | reflection |
| The bending of light waves as they passes at an angle from one medium to another | refraction |
| A mirror or lens that curves outward; makes images smaller. An example is a security mirror | convex lens |
| a mirror that curves inward. Used in a flashlight and makes images appear upside down. | concave lens |
| a mirror with a flat surface | plane mirror |
| an object that makes its own light | luminous |
| an object that reflects light | illuminated |
| objects that allow light to pass through | transparent |
| signals that uses constant little changes to capture information; can be unreliable and the information may become distorted as it is being transmitted | analog signals |
| signals that have been translated into a data stream of ones and zeros (binary code) which are made from rapid pulses that are repeatedly turned on and of. A more reliable way to send and receive information. | digital signals |
| this happens when light waves pass completely through a medium like water or glass | transmission |
| this happens when light waves do not pass through a material | absorption |
