Topics covered in Waves for BITSAT Physics.
Topics in Waves
Introduction to Waves and Types
- A wave is a disturbance that travels through a medium or space, transferring energy without transferring matter
- Mechanical waves require a medium (sound, water waves, seismic waves)
- Electromagnetic waves can travel through vacuum (light, radio waves, X-rays)
Transverse and Longitudinal Waves
- Transverse waves: particle motion perpendicular to wave direction (crests and troughs)
- Longitudinal waves: particle motion parallel to wave direction (compressions and rarefactions)
- String waves are transverse, sound waves in air are longitudinal
Wave Displacement and Parameters
- Wavelength (λ): distance between two consecutive identical points
- Frequency (f): number of oscillations per unit time
- Time period (T): time for one complete oscillation, T = 1/f
Speed of Waves
- Wave speed depends on properties of the medium, not on frequency or amplitude
- For transverse waves on string: v = √(T/μ), where T is tension, μ is linear mass density
- For sound in gases: v = √(γP/ρ) (Laplace correction to Newton's formula)
