I need this book Calculus by James Stewart 8th edition.

threshold wavelength means minimum wavelength.

Homework Statement The photo electric effect threshold wavelength of silver is 2762A(angstrum) Homework Equations Calculate the maximum kinetic energy of electron? The Attempt at a Solution since no work function then how can I slove this? Is this be sloved by E=hv-Φ?

thank you sir,

I was thinking that what is solid reason behind the failure of Classical Mechanics in Black body radiation? Why classical mechanics not explain the curve at lower or higher range of frequncies.

Thanks, Sir I was little confused but now it clears the idea to slove any kind of parabola.

How can I solve the equation of a parabola when the focus and Latusrectum are given?

I am Inam khan doing B.S Physics.My favorite field of physics is Gravition.
