Question

  

Last questions of my semester!! Would be greatly appreciated.

1)

A beam of light travels from a medium with an index of refraction of 1.29 to a medium with an index of refraction of 1.46. If the incoming beam makes an angle of 14.0° with the normal, at what angle from the normal will it refract?

2)

Light passes through a pair of narrow slits with a 0.67-mm separation. It is found that the fourth bright fringe makes an angle of 0.18° with the normal. What is the light’s wavelength in nanometers?

3)

Find the energy in joules of a single photon of microwave radiation with the wavelength of 0.66 cm.

4)

An electron’s x-velocity uncertainty is found to be 5.68×104 m/s. What is its position uncertainty in nanometers in the x direction?\

5)

Using the Bohr model, find the wavelength in nanometers of the radiation emitted by a hydrogen atom, when it makes a transition from the n = 7 state to the n = 3 state.
