You're on a roll — Here are summaries of the listed experiments: 1. Acceleration due to gravity: This experiment aims to determine the value of g, the acceleration due to gravity. Common methods involve measuring the period of a simple pendulum or the time taken for an object to fall a known vertical distance. 2. Young modulus of elasticity of an elastic material: This experiment determines the Young's modulus of a material by measuring its extension under varying tensile loads. A wire of the material is subjected to increasing weights, and the corresponding extensions are measured to plot a stress-strain graph. 3. Demonstrate Ohm's law: This experiment verifies Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature and other physical conditions remain constant. It involves measuring current and voltage across a resistor using an ammeter and voltmeter. 4. The temperature coefficient of resistance of a material: This experiment determines how the electrical resistance of a material changes with temperature. The resistance of a wire (e.g., copper or nichrome) is measured at different temperatures, often by immersing it in a temperature-controlled bath. 5. The EMF and internal resistance of a cell: This experiment determines the electromotive force (EMF) and internal resistance of a cell. It involves connecting the cell to an external variable resistor and measuring the terminal voltage across the cell and the current flowing through the circuit for different external resistances. 6. The speed of sound in air: This experiment measures the speed of sound in air. Common methods include using a resonance tube with a tuning fork to find wavelengths at different resonant lengths, or measuring the time taken for sound to travel a known distance (e.g., using echoes). 7. The wavelength of light (Young's double slit): This experiment uses Young's double-slit interference to determine the wavelength of light. Light from a monochromatic source passes through two narrow slits, creating an interference pattern of bright and dark fringes on a screen, from which the wavelength can be calculated. 8. Specific heat capacity of liquid and solid: This experiment determines the specific heat capacity of a substance (liquid or solid). It typically involves heating a known mass of the substance and measuring the temperature change for a given amount of heat energy supplied, often using an electrical heater and a calorimeter. 9. The specific latent heat of vaporization (water): This experiment determines the specific latent heat of vaporization of water. It involves supplying a known amount of heat energy (e.g., using an electric heater) to boil a measured mass of water and collecting the steam produced, measuring its mass. 10. Planck's constant and work function of a metal: This experiment investigates the photoelectric effect to determine Planck's constant and the work function of a metal. It involves illuminating a metal surface with light of varying frequencies and measuring the maximum kinetic energy of the emitted photoelectrons (or the stopping voltage). What's next?
