PreQ Physics - Term 2 Equations

Combined gas law

(p1v1)/t1 = (p2v2)/t2

Specific heat capacity

Q = mc * change(t) in J/kg/c

Specific latent heat

Q = ml

Speed of a wave

v = lambda * f

Snell’s law

n1 * sin theta1 = n2 * sin theta2

refractive index from speed of light formula

n = speed of light / velocity

refractive index from angles

n = sin i / sin r

critical angle formula

n = 1/sin c

Pressure formula in solid

P = f/a

Pressure formula in liquid

p = rhogh

density formula

Rho = m/v
