Please see the attachment for complete solution.

1. Simple harmonic oscillation is motion of the form x(t) = A sin(wt + phi), where A is the amplitude, w is the angular frequency, and phi is the initial phase.

2. The de Broglie wavelength of an object is given by lambda = h/p, where p is the momentum of the object and h is Planck's constant.

3. Since white light is not monochromatic, i.e. it consists of different colors, each with a different wavelength, one will not see a double-slit interference pattern with white light.

4. The wavelength of a wave is the distance from a crest of the wave to the next crest.

5. See the diagrams below.
