5-1 E.M. Spectrum
Electromagnetic Spectrum
| Question | Answer |
|---|---|
| A transverse wave that is a disturbance in the electric and magnetic field that carries energy(radiation). | Electromagnetic wave |
| Electromagnetic waves with the longest wavelength, that have low frequency/ energy. | Radio waves |
| Electromagnetic waves used in cellular communication and warming of food. | Microwaves |
| E.M wave that is heat, below visible light | Infrared |
| Electromagnetic waves you can see. Made of all the colors of light | Visible light |
| Electromagnetic waves with wavelengths just shorter than visible light. Waves that can cause damage to skin and eyes when not protected. | Ultraviolet |
| Electromagnetic waves that can penetrate through living tissues but are absorbed by bones. | X-rays |
| Electromagnetic waves with the shortest wavelength and the highest frequency/energy | Gamma |
| The range of all E. M waves. (7 total) | Electromagnetic spectrum |
| Name the 7 different waves that make up the E.M. Spectrum from low frequency/ energy to high frequency/ energy. | Radio waves, Microwaves, Infrared light, visible light, ultraviolet light, x-ray, gamma rays |
| How fast do E.M. waves travel in a vacuum? | Speed of light or 300,000,000m/s |
| ENERGY of E.M waves. | Radiation |
| E.M. waves travel through a vacuum at the speed of light but they can also travel through medium. What happens to the speed when they travel through a medium/matter. | Slow down |
| What color of visible light has the shortest wavelength. | Violet |
| What color of visible light has the longest wavelength. | Red |
| In E.M . waves frequency is closely related to? | Energy |
| When the frequency of a E.M. wave increases the wavelength will? | decrease |
| What is the only EM wave that we can actually see? | Visible light |
| When we talk about E. M. radiation we have learned that high energy/ frequency waves can possible cause damage to | Living tissue |
| What is the unit for frequency | Hertz |
| Hot objects give off this type of wave. | Infrared |
| What is the saying that can help you remember the order of visible spectrum? | ROYGBIV |
| Splits visible light into colors | Prism |
| The distance between 2 neighboring peaks(crest) or troughs is called | wavelength |
| The most dangerous waves which are short and can be caused from radioactivity or nuclear reactions. | Gamma |
| the number of waves that pass a given point in a given time. | Frequency |
| Electromagnetic waves are....... | Transverse |
| A wave with a large wavelength will have a ______ frequency and _____ energy | low, low |
| 18. Put the visible light colors in order from SHORTEST wavelength (highest frequency) to longest wavelength (lowest frequency) | violet, indigo, blue, green ,yellow orange red |
| Which correctly explains the relationship between the energy and frequency of a wave. | Directly related or increase in the same way |
