The video tutorial covers various physics concepts, including wave superposition, resonance, alpha particle charge, photon emission, light's wave nature, gravitational force, and the strong nuclear force. It explains how waves add their amplitudes, the phenomenon of resonance, and the calculation of an alpha particle's charge in coulombs. The tutorial also discusses photon emission in mercury atoms, evidence of light's wave nature through diffraction, and the calculation of gravitational force between Earth and the Moon. Finally, it explains the strong nuclear force that holds the nucleus together.
