Welcome to Physics Heaven, where we explore the fascinating aspects of physics and dive deep into the questions that spark curiosity. In today’s discussion, we unravel the mystery behind the question, “What is the frequency of electromagnetic radiation with wavelength 532nm?”
Understanding Electromagnetic Radiation
Electromagnetic radiation is a fundamental concept in physics. It encompasses a broad spectrum of waves, ranging from radio waves to gamma rays. These waves differ in their wavelength (λ) and frequency (ν), which are inversely related to each other.
Light with a wavelength of 532nm falls within the visible spectrum, specifically in the green region. It’s widely used in lasers, optical experiments, and scientific instruments, making it a frequent topic of interest for both professionals and enthusiasts in the field.
The Relationship Between Wavelength and Frequency
To determine what is the frequency of electromagnetic radiation with wavelength 532nm, it is essential to understand the formula that relates wavelength and frequency:
Where:
- = Frequency (in Hertz, Hz)
- = Speed of light in a vacuum (≈ 3.00 × 10⁸ m/s)
- = Wavelength (in meters, m)
The formula indicates that the frequency is inversely proportional to the wavelength. Thus, as the wavelength decreases, the frequency increases, and vice versa.
Calculating the Frequency of Electromagnetic Radiation with Wavelength 532nm
To calculate what is the frequency of electromagnetic radiation with wavelength 532nm, we first convert the wavelength from nanometers to meters:
Substituting the values into the formula:
Thus, the frequency of electromagnetic radiation with a wavelength of 532nm is approximately 5.64 × 10ⁱ⁴ Hz.
The Significance of 532nm Wavelength
