A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n = 3excited state. The atom returns to the ground state by emitting two photons. What are their wavelengths? ? m (lowest energy photon) ? m (highest energy photon)
A small air bubble is placed 0.04 m inside a glass sphere of refractive index 1.5. When viewed normally from outside it is seen at a depth of 0.03 m. Determine the radius of curvat
To test the deflection of the uniform 400N/m beam the 600N boy exerts a pull of P42N on the rope. The distance between the rope and the support at A is P43 metres. Assume the pull
Why is the Kinetic energy of the system minimum in the frame of the center of mass for any number of particles solution) The kinetic energy of any entity depends on the reference
Explain the meaning of Diffraction The spreading of a wave around a corner or through a slit of width b, which is about an order of magnitude of the size of the wavelength, is

filled observation of youngs modulus using searles apparatus
What is the difference between the Atomic Theory and the Kinetic Theory? Atomic theory is all about structure of an atom, i.e., its composition. Like an atom in general is made
construction & working.
Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
