Question

Длина электромагнитной волны (в вакууме) равна 600 нм. Определите, чему равна ее частота и к какому виду излучений она относится.

Answer 1

Determining the Frequency and Type of Electromagnetic Radiation

To determine the frequency of an electromagnetic wave, we can use the equation:

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

Given that the wavelength of the electromagnetic wave in vacuum is 600 nm, we can calculate its frequency using the speed of light, which is approximately 299,792,458 meters per second (m/s).

Frequency (f) = 299,792,458 m/s / 600 nm

To convert the wavelength from nanometers (nm) to meters (m), we divide by 1 billion (1 nm = 1/1,000,000,000 m).

Frequency (f) = 299,792,458 m/s / (600 nm / 1,000,000,000)

Simplifying the equation:

Frequency (f) ≈ 499,654,096,666,667 Hz

Therefore, the frequency of the electromagnetic wave is approximately 499,654,096,666,667 Hz.

Now, let's determine the type of electromagnetic radiation to which this wavelength corresponds. Electromagnetic radiation spans a wide range of wavelengths, from radio waves to gamma rays. The wavelength of 600 nm falls within the visible light spectrum, which ranges from approximately 400 nm to 700 nm.

Therefore, the electromagnetic wave with a wavelength of 600 nm belongs to the visible light spectrum.
