![**Question:**
For electromagnetic radiation, when wavelength goes UP, frequency goes DOWN.
- ○ True
- ○ False
**Explanation:**
This question addresses the inverse relationship between wavelength and frequency in electromagnetic radiation. According to the electromagnetic spectrum principles, as the wavelength of electromagnetic radiation increases, its frequency decreases. This relationship is described by the equation:
\[ c = \lambda \nu \]
where:
- \( c \) is the speed of light in a vacuum,
- \( \lambda \) is the wavelength,
- \( \nu \) is the frequency.
Since the speed of light is constant, an increase in wavelength results in a decrease in frequency. Thus, the statement is **True**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb07cb39e-ddbc-44ff-927a-80f9ff3bbc4d%2F37d67eb2-1ea8-4b9b-9fed-ff90f1be6bf3%2Fujnh7s_processed.png&w=3840&q=75)

Transcribed Image Text:**Question:**
For electromagnetic radiation, when frequency goes UP, energy goes DOWN.
**Options:**
- ○ True
- ○ False
**Explanation:**
This statement refers to the relationship between frequency and energy in electromagnetic radiation. According to Planck's equation, energy and frequency are directly proportional. Therefore, the correct answer is "False."
