Radiation: The process of the transfer of the heat from one place to another place without heating the intervening medium is called radiation. For example, the heat from the sun reaches the earth through radiation mode. They can reflect and refract like light waves.

The incorrect statement isa)convection current causes trade windsb)tra...
Incorrect Statement: C: Radiation requires medium for heat flow
Explanation:
Conduction, convection, and radiation are three different methods of heat transfer. Let's break down each statement to identify the incorrect one:
1. Convection current causes trade winds:
- This statement is correct. Convection currents play a significant role in the formation of trade winds, which are global wind patterns caused by the uneven heating of the Earth's surface.
2. Transmission of heat without actual movement of particles is called conduction:
- This statement is correct. Conduction is the transfer of heat through direct contact between particles or objects without the actual movement of particles.
3. Radiation requires medium for heat flow:
- This statement is incorrect. Radiation is a method of heat transfer that does not require a medium. It can occur through empty space, unlike conduction and convection. Radiation involves the emission of electromagnetic waves, such as infrared radiation, which carry thermal energy.
4. In convection, heat is transferred through the movement of fluid:
- This statement is correct. Convection is the transfer of heat through the movement of a fluid (liquid or gas). When a fluid is heated, it becomes less dense and rises, while the cooler fluid descends to take its place, creating a convection current.
Therefore, the incorrect statement is C: Radiation requires medium for heat flow.
