42:55 isnt conceptual or theoretical peak, its basic concept that ejection of electrons only depend on frequency of light and not on anything else at all whether it is power/intensity. So only the light with higher frequency or energy will emit photoelectron and we know that UV rays have really high energy/frequency

Hey could u explain at 30:05 sir multiplied by 100?

[@dakshrana5538]

1:04:00 can we use this manupulation for this que F= 2P/c (for reflecting surface) soo pressure on hemisphere due to light source Pressure = 2*(Power)/c*4pi*R^2 (intensity change at distance R) Since the projected portion of force is a Circle of Area pi*R^2 (usual assumption) Fnet = 2P*(pi*R^2)/c*(4piR^2) tho answer through this method matches .. **But we have to go through the integration method for any other shape like cone
