A scientist designs an experiment in which a light source is pointed at a substance and a light detector is placed on the opposi
te side of the substance.
When the light source is turned on, the scientist observes that no light is detected on the far side of the substance. What is the best interpretation for this observation?
A. The light was either reflected or transmitted by the substance.
B. The light was both absorbed and reflected by the substance.
C. The light was both reflected and transmitted by the substance.
D. The light was either absorbed or reflected by the substance.

Answer:
A 5
Explanation:
The wave with the least amount of wavelength will have the greatest amount of energy.
Wavelength and energy shares an inverse relationship;
E = h f =
From this equation, we see that the higher the energy of a wave, the lesser its wavelength.
- Choice A from the options has the least wavelength.
- Wavelength is the distance between two successive crests of a wave.
This is why we see that in the electromagnetic spectrum, radio waves have the least energy because they have the longest wavelength.
