STUDY

what is the em spectrum and what do you know from it

it is a complete range of all types of electromagnetic radiation and you know

what is the full em spectrum, colors and types of rays

colors from longest wavelength to shortest-

red- lowest energy

orange

yellow

green

blue

indigo

violet- the highest energy

types from lowest to highest energy-

Radio Waves: Longest wavelengths, lowest frequency (e.g., AM/FM radio, Wi-Fi, cell phones).

Microwaves: Used for radar, communication, and heating food.Infrared: Felt as heat; used in night vision and thermal imaging.

Visible Light: The only part of the spectrum detectable by the human eye.

Ultraviolet (UV): Invisible to humans, responsible for sunburns; used in sterilization.

X-rays: High energy, capable of penetrating soft tissues (e.g., medical imaging).

Gamma Rays: Shortest wavelengths, highest energy; produced by radioactive decay and cosmic explosions.

what are all the relationships and what do they mean

Direct (Positive) Relationship: Both variables increase or decrease together (e.g., as temperature increases, kinetic energy increases)

Linear vs. Non-Linear: Variables change at a constant rate(linear) or at an accelerating/decelerating rate (exponential)

What is the Doppler Effect?  What effect does the Doppler Effect have on light and waves? 

the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It explains why an ambulance siren sounds higher-pitched as it approaches and lower-pitched as it drives away.

it is because wave crests bunch together making a higher energy higher pitched noise since it had blueshift but when it drives away the crests elongate spreading apart created a lower energy lower pitch noise.
