When a compact disc (CD) is viewed in sunlight, the colors similar to those of a rainbow are seen due to the phenomena of reflection and diffraction. The CD’s surface consists of closely spaced tracks that act as a diffraction ...
Water in an electric kettle gets heated primarily due to conduction. The heating element transfers thermal energy directly to the water molecules upon contact. While convection and radiation may contribute minimally, the main mechanism responsible for heating water in an ...
The Sun’s heat reaches the Earth primarily through radiation. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, traveling through the vacuum of space.
In the method of heat transfer known as radiation, a medium is not necessary. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, that can travel through a vacuum, such as space. Unlike ...
