Is the velocity of two photos of same radiation(light) with different energies same ?? (also in Same medium)

Will energy alter the velocity of photon?

The photon is a quantum object and one cannot assign a velocity to it.

Classical light always travels at c in a vacuum for all frequencies. In a medium like glass or water light will appear to slow down.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
