The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.

The source of solar power is energy carried by the electromagnetic waves radiated by the Sun. Most of this energy is carried by visible light and infrared (heat) radiation.
The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Electromagnetic spectrum and visible light.
Laboratory Manual. Montana State University-Billings. Lab # 1 Specific Heat and Calorimetry. Theory: The specific heat (c) of an object is defined by the equation that relates the heat energy (Q) absorbed by an object of mass m to its corresponding increase in temperature (∆T): Q = mc∆T.
Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and changes through your system.
In this chapter, we study the basic properties of light. In the next few chapters, we investigate the behavior of light when it interacts with optical devices such as mirrors, lenses, and apertures. 1.1: Prelude to The Nature of Light. Maxwell’s equations predict the existence of electromagnetic waves and their behavior.
Q1. What are the different modes of heat transfer? Conduction. Convection. Radiation.
