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
