On a summer day, you feel the warmth of electromagnetic radiation from the sun. Which statement explains the type of model that best describes this phenomenon?
The wave model is best because the radiation carries energy.***
The particle model is best because the radiation travels through empty space.
The particle model is best because the radiation has a well-defined wavelength.
The wave model is best because the radiation cannot travel through matter.
The correct answer is: The particle model is best because the radiation travels through empty space.
The correct answer is: The wave model is best because the radiation carries energy.
To explain this, let's look at the different models of electromagnetic radiation.
1. The wave model describes electromagnetic radiation as a form of energy that travels through space as waves. This model suggests that electromagnetic waves, including the radiation from the sun, carry energy and can transfer that energy to other objects. The warmth you feel on a summer day is a result of this energy transfer.
2. The particle model, also known as the corpuscular model, describes electromagnetic radiation as a stream of particles called photons. According to this model, radiation travels through empty space as discrete packets or quanta of energy. However, the statement in question mentions that the radiation carries warmth, which suggests the transfer of energy in a continuous form, more aligned with the wave model.
3. The statement does not mention anything about the radiation having a well-defined wavelength, so it is not relevant to the explanation.
4. The wave model is not dependent on the radiation's ability to travel through matter. Electromagnetic waves can indeed travel through empty space, vacuum, or various materials. The ability to travel through matter is a characteristic of both particle-like and wave-like behavior of electromagnetic radiation.
Therefore, the most suitable model to explain the phenomenon described in the statement is the wave model because it correctly captures the idea that electromagnetic radiation carries energy.
