Final answer:
The statement is false. The energy of electromagnetic radiation decreases as the wavelength increases, meaning that longer wavelengths correspond to lower energy.
Step-by-step explanation:
Regarding the electromagnetic spectrum, the statement that the longer the wavelength the higher the energy is (b) False. In fact, it is the opposite. The energy of electromagnetic radiation is directly proportional to its frequency and inversely proportional to its wavelength. Therefore, the longer the wavelength, the lower the energy of the radiation. Conversely, the shorter the wavelength, the higher the energy.
Additionally, if one compares different colors of light, such as blue light and red light, blue light has a shorter wavelength and, therefore, a higher energy than red light. This is a fundamental concept in understanding how the electromagnetic spectrum works. A helpful analogy might be moving a heavy rope: making short, tight waves requires more energy than creating long, wide waves.
