Equation for speed/velocity

Speed= Distance/Time
Equation for mass

Mass=Density x Volume
Equation for power

Power=Work done/Time
What is the wave equation

V= Frequency x Wavelength
Equation for refractive index

Refractive index= Speed of light in vacuum/ Speed of light in material (C/V)
Equation to find critical angle

sinC=1/n (refractive index)
What is the equation for finding the path difference in Young's double slit experiment
- Path difference= separation of double slits x fringe separation / distance from slits to the screen
- Path difference= ay/d
What equation is used to find the wavelength at the first point above the axis of symmetry in Young's double slit experiment
since it is the first oder n=1
- ay/d=n x Wavelength
- so Wavelength= ay/d
what is the equation for energy in a photon
- E=hf
- E= Planck's constant x frequency of radiation
If the energy of the photon is greater than the work function, what is the equation used to find the KE from the electrons

hf-work function=1/2 x m(v squared)
What equation is used to find the threshold frequency

work function=h x threshold frequency
What equation can be used to find the frequency of a photon emitted or the energy difference between two levels

hf= change in E
What equation can be used to find the minimum wavelength of an x-ray photon

E of X-ray photon= hc/ min wAvelength =eV
What is the equation for a wavelength associated with a particle having a momentum
- Wavelength= h/p
- where wavelength is de Broglie wavelength
- h is Planck's constant
- p is the momentum of the particle
