Question

In the visible spectrum, the color of light depends on the frequency. Which statement BEST describes the wavelengths of a certain frequency?
A) A low frequency wave has a long wavelength.
B) A low frequency wave has a short wavelength.
C) A high frequency wave has a wavelength that is not measurable.
D) A high frequency wave and a low frequency wave have the same wavelengths

Answer 1

answer is A trust me it is i"m taking biology in 6th grade and that is a high school class.

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

It is know that wavelength is inversely proportional to the frequency.

Mathematically,       $\lambda = \frac{c}{v}$

where           $\lambda$ = wavelength

                               v = frequency

                               c = speed of light

Therefore, when there will be increase in wavelength then there will be decrease in frequency and vice-versa.

Hence, we can conclude that the statement a low frequency wave has a long wavelength best describes the wavelengths of a certain frequency.
