Theory,

relevant equations, focus of the investigation, relevant diagrams

Procedure

and materials used, a sketch/photo of the experimental setup and uncertainties

Relevant

equations in a correct format (typeset)

Both

A and C

All tables, figures, and graphs should be appropriately referenced in the text

Self-contained

captions are required for figures, tables and graphs

All of the above

High-quality

labelled diagrams or photos of the experimental set-up must be included, even

if the method is detailed

That light was particle-like in nature

The quantum nature of light as photons

The wave-particle duality of light

That light was wave-like in nature

That different frequencies of light have differing energies

Point sources of light used to determine the wave like nature of light

A bright point that appears at the centre of a circular object's shadow

Radial lines around the centre of a circular objects shadow

Concentric circles around the centre of a circular objects shadow
