Study Notes
Wave Nature of Light
- Diffraction is the spreading out of a wave into its geometric shadow as it passes through a gap, or around an obstacle, of roughly the same width as its wavelength.
- Interference occurs when two or more waves from different sources overlap, forming a single resultant wave of different amplitude.
Interference Patterns
- Young's Double Slit Experiment demonstrates constructive and destructive interference of light waves.
- The primary formula used in calculations involving interference patterns is nλ = dsinθ.
- In this formula: • n = order of diffracted image • λ = wavelength of light source • d = grating constant • θ = angle between zero order image and observed image
Measuring Angle of Interference
- To measure θ, the angle between zero order image and observed image, a spectrometer is commonly used.
- A spectrometer consists of various parts, which enable measurement of the angle of interference.
Electromagnetic Spectrum
- Differing wavelengths of light are separated into different categories known as the electromagnetic spectrum.
