Difficulty: Easy

Concept notes: The Sun emits energy in various forms, but the primary forms that reach the Earth are light and thermal energy.

Common Mistakes: A common misunderstanding is that mechanical energy is a form of energy directly transmitted from the Sun to the Earth. However, mechanical energy is not a form of energy that the Sun directly transmits to the Earth.

Explanations: The Sun emits energy primarily in the form of electromagnetic radiation, which includes visible light and infrared radiation (thermal energy). These forms of energy travel through space and reach the Earth. Mechanical energy, such as sound or motion, is not a form of energy that the Sun directly transmits to the Earth.

Option Analysis:

Option A: Light and Mechanical. This option is incorrect because mechanical energy is not a form of energy that the Sun directly transmits to the Earth.
Option B: Light and Thermal. This option is correct because the Sun emits light and thermal energy, which are the primary forms of energy that reach the Earth.
