How to Use This Calculator

In the Tunneling section, enter Particle Energy (eV), Barrier Height (eV), and Barrier Width (m) to compute transmission probability.
Switch to Photoelectric Effect and enter Photon Wavelength (nm) and Work Function (eV) to see maximum kinetic energy of ejected electrons.
Use the Compton Scattering section: enter Incident Wavelength (nm/Å) and Scattering Angle (°) to compute wavelength shift Δλ.
In Blackbody Radiation, enter Temperature (K) to get peak wavelength from Wien's law and compare to visible spectrum.
Check the Tunneling chart showing Transmission vs. Barrier Width to visualize exponential suppression.

What each input means

T ≈ e^(-2κa) | KE = hf - φ | Δλ = λ_c(1-cos θ) | λ_peak = b/T
