Waves
| Question | Answer |
|---|---|
| What is the correct term for the distance of a wave from one crest to the next? | Wavelength |
| ________ are rhythmic disturbances that carry energy through matter and space. | Waves |
| True or false: Electromagnetic waves require a medium to travel through. | False |
| Waves with a higher frequency have ____ wavelengths in a given amount of time than other waves. | More |
| Sound travels in _______ waves. | Longitudinal |
| Electromagnetic energy travels in _______ waves. | Transverse |
| A _______ is where the particles in a longitudinal wave are pushed together. | Compression |
| A _______ is where the particles in a longitudinal wave spread out. | Rarefaction |
| True or false: Mechanical waves require a medium to travel through. | True |
| Particle motion is perpendicular to the motion of the wave in which type of wave? | Transverse |
| What is frequency? | The number of waves that pass a point in one second |
| How are frequency and wavelength related? | When frequency increases (more waves) wavelength decreases (waves get shorter). When frequency decreases (fewer waves) wavelength increases (waves get longer) |
| When a wave bounces off of a surface it is called _______. | Reflection |
| What are rsdio waves used for? | Communication |
| What are microwaves used for? | Cooking |
| What are infrared waves used for? | Night vision goggles |
| What are ultraviolet waves used for? | Kill bacteria |
| What are x-rays used for? | Check for broken bones |
| What are gamma rays used for? | Treat cancer |
| The angle waves hit the surface of a material is the same as the angle at which they bounce off. This kind of wave behavior is called _____. | Reflection |
| When placed in water, a pencil appears to bend as it enters the water. However, if you took it out you would see it is perfectly straight. What wave behavior causes this? | Refraction |
| What is the best explanation for why refraction occurs? | As light waves move to a new medium, they slow down and bend |
| What best explains how a prism works? | White light enters the prism and each color bends a different amount, separating the colors |
| What energy conversion occurs when light waves are absorbed by an object? | Radiant to thermal |
| When two or more waves combine to form a new wave, it is called _____. | Interference |
