객관식
Which of the following best describes the relationship between the wavelength (λ) and frequency (ν) of light?
A
They are both constant for all types of light.
B
They are inversely proportional; as wavelength increases, frequency decreases.
C
They are directly proportional; as wavelength increases, frequency also increases.
D
They are unrelated; wavelength and frequency do not affect each other.

Recall the fundamental relationship between the speed of light (c), wavelength (\\(\lambda\)), and frequency (\\(\nu\)), which is given by the equation:
\(c = \lambda \times \nu\)
Understand that the speed of light (c) in a vacuum is a constant value, approximately \(3.00 \times 10^{8}\) meters per second.
Since $c\( is constant, if the wavelength (\\)\lambda\() increases, the frequency (\\)\nu$) must decrease to keep the product \(\lambda \times \nu\) equal to \(c\).
This means wavelength and frequency are inversely proportional to each other, which can be expressed as:
\(\nu = \frac{c}{\lambda}\)
Therefore, the correct description is that wavelength and frequency are inversely proportional; as wavelength increases, frequency decreases.
