What does the Greek symbol λ (Lambda) mean?
Wavelength
What is the speed of light?
3.00x10^8 m/s
What is C?
The speed of light
What is h?
Planck's constant
What is Planck's Constant?
6.626x10^-34 J/Hz
What is the formula for Energy?
E=hv
What is the formula for frequency(Nu)?
v= c/λ
What is the formula for λ?
λ=c/v
What is the formula for C?
c = λv
(1) What is the formula for relating wavelength and frequency?
speed = wavelength x frequency (c=λν)
How are wavelength and frequency related?
shorter wavelength = higher frequency , longer wavelength = lower frequency
(2) What is the formula for relating energy and frequency?
E=hv
How are energy and frequency related?
greater the energy larger the frequency and vice versa
