Study Notes
Electromagnetic Waves
- Electromagnetic waves form a continuous series with varying wavelength and frequency, including radio waves, microwaves, infrared, visible light, X-rays, ultraviolet, and gamma rays.
Electromagnetic Spectrum
- The electromagnetic spectrum can be arranged in order of wavelength, starting with the longest wavelength: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
- The electromagnetic spectrum can also be arranged in order of energy, starting with the highest energy: gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves.
Wavelength vs. Frequency
- The wave speed (v) can be calculated from the frequency (f) and wavelength (λ) using the formula: v = λ x f.
- The speed of light (c) is 3 x 10^8 m/s.
Energy vs. Frequency
- The energy (E) of a wave is related to its frequency (f) by the equation: E = h x f.
- Planck's constant (h) is 6.63 x 10^-34 J s.
The Nature of Electromagnetic Waves
- Electromagnetic waves are transverse waves made up of electric and magnetic fields.
- All electromagnetic waves travel at the same speed in a vacuum, which is 3 x 10^8 m/s.
- Electromagnetic waves have electric and magnetic fields that oscillate perpendicular to the direction of wave propagation.
Wave Characteristics
- The wavelength (λ) of a wave is the distance between two matching points on neighboring waves.
- The amplitude of a wave is the maximum distance a point moves from its rest position.
- The frequency (f) of a wave is the number of waves passing any point each second.
Electromagnetic Wave Propagation
- Electromagnetic waves transmit and propagate through electromagnetic radiation, which releases during events like sunsets.
- Radio waves can be used for transmission.
Types of Electromagnetic Waves
- The electromagnetic waves are grouped into types with similar wavelengths and properties, including radio waves, microwaves, infrared, visible light, X-rays, ultraviolet, and gamma rays.
