Waves

Wave Characteristics

• Wave: a disturbance that travels through a medium from one location to another location.
• Mechanical Wave: Unlike the electromagnetic wave, this wave does not travel through a vacuum
• Electromagnetic Wave: Any type of wave that is found on the Electromagnetic Spectrum
• Wavelength: Distance between two corresponding points
• Frequency: The number of occurrences of a repeating event per unit of time

v SPEED OF A WAVE v Speed = Distance / Time

Sound

• Sound: Vibrations that travel through the air or other medium, and can be heard when the ear is reached
• Reflection: When a sound bounces off of a surface or medium
• Diffraction: The bending of waves over small corners and the spreading of them over small openings, ex. hearing a sound from around a corner
• Doppler Effect: An increase or decrease in the frequency of sound as the sound source moves closer or farther away, like an ambulance driving past a street

• How does the medium affect sound?

Different materials can affect the speed of sound

Electromagnetic Spectrum

• Speed of waves in vacuum:

Radio: 10^4 Hz, transmitted by the radio lmao Microwaves: 10^8 Hz, transmitted by microwave ovens and stuff Ultraviolet: 10^16 Hz, transmitted by the sun, very powerful and kills lots of stuffX-Rays: 10^20 Hz, found in x-ray tubes, considered "ionizing radiation: Gamma Rays: 10^24 Hz, found in SPACE AND STUFF, DEADLY STUFF
