Final answer:
To confirm the transfer and transformation of wave energy to a medium, you can measure the increase in temperature of the medium or measure the decrease in amplitude or intensity of the wave.
Step-by-step explanation:
An electromagnetic wave can be absorbed by a medium, such as when light is absorbed by a material. To confirm the transfer and transformation of wave energy, a measurement that can be made is measuring the increase in temperature of the medium. This increase in temperature indicates that the energy of the wave has been transformed into thermal energy.
For example, when sunlight shines on a black surface, the black surface absorbs most of the light waves and converts them into thermal energy. This can be confirmed by placing a thermometer on the black surface and measuring the increase in temperature.
Another measurement that can be made is measuring the intensity or amplitude of the wave before and after it interacts with the medium. If the amplitude or intensity of the wave decreases after interacting with the medium, it indicates that energy has been transferred and transformed.
