Study Notes
Wave Calculations
- Waves originate from vibrations, transferring energy from one point to another without transferring matter.
- Key parts of a wave include:
- Crest (peak): Highest point.
- Trough (valley): Lowest point.
- Amplitude: Height from rest position to crest/trough. Base unit: meters (m).
- Wavelength (λ): Length of one full wave. Base unit: meters (m).
- Frequency (f): Number of waves per second. Base unit: Hertz (Hz).
- Period (T): Time to complete one full wave. Base unit: Seconds (s).
- Formulas:
- Speed (v) = frequency (f) × wavelength (λ) (v = fλ)
- Frequency (f) = 1 / period (T) (f = 1/T)
- Period (T) = 1 / frequency (f) (T = 1/f)
- Relationship between frequency and wavelength:
- Inversely proportional; as one increases, the other decreases.
- Speed of light (c) is a constant 3.00 × 10⁸ m/s in a vacuum.
- The electromagnetic spectrum categorizes waves based on frequency and wavelength, including radio, microwave, infrared, visible, ultraviolet, X-ray, and gamma rays.
Practice Questions - Multiple Choice
- Wave properties: Energy transfer, not matter transfer.
- Frequency increase leads to wavelength decrease (inverse relationship).
- Light colour identification based on wavelength.
Practice Questions - Short Answer
- Calculation of period and frequency for given conditions.
- Speed calculation using frequency & wavelength.
- Wave properties analysis (labeling crest, trough, rest, wavelength, and amplitude, calculation of period, and frequency) .
- Calculation of wave speed using given values.
- Determination of electromagnetic radiation type based on frequency.
