What is the equation for phase difference?
2[radian] —————— x Path difference wavelength [Can be re-arranged to get path difference as subject]
What is an alternative equation for power?
Power= n h f where n = no. photons where h is planck’s constant and f is frequency
What is the equation for specific charge?
Charge / Mass = ?Ckg^-1
What equation can be used to find a harmonic?
fn = nfo Fn = nth harmonic N = the harmonic you have O= fundamental frequency
What is the equation to find the separation of fringes?
w= λD/s w= Separation of fringes (m) λ= wavelength of light source (m) D= distance between double slit and screen s= distance between the slits
How to find the distance between the slits of a diffraction grating?
1/ no. of slits
One Amp equals how many Coulombs?
1A=1C
