In the spectrum of visible light, the red light has_ _ _ _ wavelength and _ _ _ _ frequency.

A) minimum, maximum

B) maximum, minimum

C) maximum, maximum

D) minimum, minimum

In the spectrum of visible light, red light has the longest wavelength and the lowest frequency compared to other colors. Therefore, the correct answer to your question is A) minimum, maximum. Let's break this down further to understand why this is the case.

Understanding Wavelength and Frequency

Wavelength and frequency are two fundamental properties of light that are inversely related. This means that as the wavelength increases, the frequency decreases, and vice versa. The visible spectrum ranges from violet light, which has the shortest wavelength and highest frequency, to red light, which has the longest wavelength and lowest frequency.

Visible Light Spectrum

• Violet: Approximately 380 nm (nanometers) - highest frequency
• Blue: Approximately 450 nm
• Green: Approximately 495 nm
• Yellow: Approximately 570 nm
• Orange: Approximately 590 nm
• Red: Approximately 620-750 nm - lowest frequency

As you can see, red light sits at the end of the visible spectrum, which means it has the longest wavelength, typically ranging from about 620 to 750 nanometers. In contrast, violet light, at the opposite end, has a wavelength of about 380 nanometers.

Frequency Relationship

The frequency of light is calculated using the formula:

Frequency (f) = Speed of Light (c) / Wavelength (λ)

Since the speed of light is constant (approximately 3 x 10^8 meters per second), a longer wavelength (like that of red light) results in a lower frequency. For red light, the frequency is around 400 terahertz (THz), which is significantly lower than that of violet light, which can be around 790 THz.

Real-World Analogy

Think of wavelength and frequency like the distance between waves in the ocean. If you have large, slow waves (long wavelength), they come less frequently (low frequency). In contrast, if you have small, fast waves (short wavelength), they arrive more often (high frequency). This analogy helps illustrate the relationship between wavelength and frequency in light.

Summary

To summarize, red light has a long wavelength and a low frequency, making it the color with the minimum frequency and maximum wavelength in the visible spectrum. Thus, the correct answer to your question is A) minimum, maximum. Understanding these concepts is crucial in fields such as physics, optics, and even photography, where light properties play a significant role.
