Текст песни Interference & Diffraction - Max Charles

Look all around you, interference and diffraction
From every surface there's reflection and refraction
We understand these phenomena from waves
So, it is clear that's the way that light behaves

Look all around you at the EM radiation
Electric and magnetic fields in oscillation
Travelling through a vacuum at speed c
C/n, considered generally

Light's a wave, but it behaves like a particle too
That's the way it can do all the things it can do
Light's a wave like a swell on stormy seas
Light displays wave properties
Like phase, amplitude, wavelength, and frequency

Laser on a double slit projected on a screen
See a pattern of bright spots, with dark spots in between
Light emitted from each slit will interact and interfere
When the path difference is one full wave
A bright spot will appear

Laser light on a single slit, what do we observe?
Light diffracts through the opening, the wavefront seen to curve
Many secondary sources of light each emitting waves
But light plus light equals dark
When those sources are out of phase

Light's a wave, but it behaves like a particle too
That's the way it can do all the things it can do
Light's a wave like a swell on stormy seas
Light displays wave properties

Light's a wave, but it behaves like a particle too
That's the way it can do all the things it can do
Light's a wave like a swell on stormy seas
Light displays wave properties
Like phase, amplitude, wavelength, and frequency
