1. Properties Of Light

Question 1

Demonstration of the wave like nature of light

Answer 1

Young’s double slit experiment

Question 2

Demonstration of the particle nature of light

Answer 2

The photoelectric effect

Question 3

Demonstration if the wave and particle natures of light

Answer 3

Passing a single electron through youngs double slit experiment, then repeating this. Each photon hots the screen at a seemingly random position, but as more arrive a diffraction pattern emerges meaning the photons were interfering with themselves

Question 4

Define monochromatic flux

Answer 4

The energy falling on a unit area, per unit time, at a given frequency

Question 5

Define bolometric flux

Answer 5

The energy falling in a unit area, per unit time, across all wavelengths

Question 6

Define luminosity

Answer 6

The total energy emitted by a source in all directions

Question 7

Monochromatic luminosity

Answer 7

The energy emitted by a source in unit time, per unit wavelength

Question 8

Bolometric luminosity

Answer 8

The total energy emitted by a source per unit time, at all wavelengths
