### Syllabus

Heat • Temperature and Heat: Heat as a form of energy, Temperature scales and measurements • Heat capacity and Latent heat • Thermal expansion: coefficient of linear expansion for solids, coefficient of volume expansion for liquids • Conduction: mechanism of conduction, definition of thermal conductivity, temperature distribution along a uniform bar of one or more substances • Convection, Newton's Law of Cooling. Note: qualitative approach only • Radiation: black bodies, Wein's law, Stefan's law Gases • Measurement of pressure • Ideal gas laws, p-V, p-T and V-T relationships • Equation of state: pV=nRT • Kinetic theory for gases, the assumptions and derivation of • pV= 1/3Nm • 1st Law of thermodynamics • Processes and cycles Vibrations • Amplitude, period, frequency and phase, T=1/f = 2π/ω • Simple harmonic motion x = Asin(ωt+ϕ), • v = ωAcos(ωt+ϕ), a = −Aω 2sin(ωt+ϕ), maximum values of v and a • Difference between free and forced vibrations; resonance. Note: Qualitative approach Waves • Speed of waves, wavelength, frequency, amplitude and phase v=fλ • Difference between longitudinal and transverse waves • Travelling wave equation. Note: No derivation • Principle of superposition of waves • Standing waves in stretched strings and pipes Light • Reflection at a plane boundary • Refraction: refractive index, relationship to wave speed, critical angle and total internal reflection • Interference: coherent sources, two source interference • Diffraction: single and double slit diffraction and diffraction gratings • The electromagnetic spectrum; orders of magnitude for f and λ
