Light Frequency (v): wave/second; wave per second measured in Hertz (Hz) Wavelength (): length of wave, measured in nm Longer wave length===>lower energy===>low frequency Wavelength and frequency are inversely proportional wavelength X frequency = c (speed of light) White light can hit the wall and make it bounce back (Reflection) • Light can also hit the wall and the wall can absorb the light (Absorption) • Light can transmit through as wall and will refract. (Transmission) • Isotope Potassium-40 how many neutrons are in the isotope? 21 neutrons • How many are protrons? There are 19 protons • How abundant is this isotope in nature? This isotope is not very abundant. • ROYGIB

Light Frequency (v): wave/second; wave per second measured in Hertz (Hz)
Wavelength (): length of wave, measured in nm
Longer wave length===>lower energy===>low frequency
Wavelength and frequency are inversely proportional
wavelength X frequency = c (speed of light)
White light can hit the wall and make it bounce back (Reflection) Light can also hit the wall and the wall can absorb the light (Absorption) Light can transmit through as wall and will refract. (Transmission)
Isotope Potassium-40
how many neutrons are in the isotope? 21 neutrons How many are protrons? There are 19 protonsHow abundant is this isotope in nature? This isotope is not very abundant.
