Final answer:
The wavelength and frequency of light are indeed inversely proportional, validated by the consistent speed of light and represented by the equation c = λf, where changes in one inversely affect the other.
Step-by-step explanation:
The statement that the wavelength and frequency of light are inversely proportional is true. As the wavelength of light increases, its frequency decreases, and vice versa. This relationship can be described by the equation c = λf, where c is the speed of light in a vacuum, λ is the wavelength, and f is the frequency. Since the speed of light is a constant, changing the wavelength will inversely affect the frequency. This can be observed in various parts of the electromagnetic spectrum, where different types of electromagnetic radiation have corresponding wavelengths and frequencies.
