I'm being confused between a Physics past exam paper book and a Physics study guide.
Is the escape velocity derived from EK + EP = 0 (this makes the escape velocity depend on the mass of the body to escape from i.e. Earth or a planet) or EK = EP (this makes the escape velocity depend on the mass of the escaping object) ?
(Where EK = 0.5mv2 and EP = - GmM/r)Also, the final step I must take in conquering the necessary Quantum Physics is the Black Body Radiation curve.
Why is there a very large maximum point (or peak), say at approximately 210nm then a sudden plummet in the curve after this ?
Where is this extra large intensity emitted from ?
