science

opaque

can't pass thru

energy conversions

change from one form of energy to another

parts of an electro magnetic spectrum

radio waves/ microwaves/ infrared/ visible light/ ultra violet/ X-rays/ gamma rays

energy

ability to do work

why is an apple red

bc the light bounces off the apple causing the color

why is the moon a silent place

bc there's no matter in space

convex lens

bends light inward

concave

bends light out

law of reflection

bounce something it will bounce back at same angle

reflected

bounces back

translucent

can go thru but isn't clear

speed of sound changes in solid

can pass theough easily

speed of sound in liquid and gases

cant go through well

law of consevation of energy

energy cannot be created or destroyed

transmitted

goes in doesn't come out

refraction

goes in then gets bent/ glasses

transparent

goes thru clearly

lumilated

has light already on its own

illuminated

has light shining on it

amplitude/ loudness

higher amp higher sound

frequency/pitch

higher frequency higher pitcg

properties of sound

medium longitudinal wave

potential/kinetic

potential is stored energy and kinetic is doing work

parts of wave

qmplitude crest trough wavelength frequency

echolocation and ocean depth

send out signal that you can hear in water

7 types of energy

sound light heat mechanical chemical kinetic potemtial

three differences between sound and light

sound- can't travel thru vacuum longitudinal wave/ light- transverse wave and can travel thru vacuum

prism

splits white light into all diff colors / rainbow

absorbed

take in

trasverse and longitutianal

transverse is for up and down movemens and longitutinal is for back and forth

properties of light

vacuum transverse wave

frequency and wavelength

wavelength is distance between one part of wave frequency is number of waves moving
