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 differenceÂ 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 WavelengthÂ
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
