Question

. У перших експериментах по вивченню поширення електромагнітних хвиль в повітрі були виміряні довжина хвилі 50 см і частота випромінювання 500 МГц. Чому дорівнює швидкість світла на основі цих неточних значень?

Answer 1

Ответ:

Лямда - 0,5

Лямда - 0,5V - 500 МГц=500•10⁸Гц

Лямда - 0,5V - 500 МГц=500•10⁸Гцс - ?

Лямда - 0,5V - 500 МГц=500•10⁸Гцс - ?с= 500•10⁸•0,5=250•10⁶м/с

The Relationship Between Wavelength, Frequency, and the Speed of Light

In the given scenario, the wavelength of the electromagnetic wave is measured to be 50 cm, and the frequency of the radiation is measured to be 500 MHz. We can use these values to calculate the speed of light.

The speed of light (c) is a fundamental constant in physics and is approximately equal to 299,792,458 meters per second (m/s). It is the maximum speed at which information or energy can travel in the universe.

The relationship between the wavelength (λ), frequency (f), and the speed of light (c) is given by the equation:

c = λ * f

Where: - c is the speed of light - λ is the wavelength - f is the frequency

To find the speed of light based on the given wavelength and frequency, we can rearrange the equation as follows:

c = λ * f

Substituting the given values: - λ = 50 cm = 0.5 meters (since 1 meter = 100 cm) - f = 500 MHz = 500,000,000 Hz (since 1 MHz = 1,000,000 Hz)

c = 0.5 meters * 500,000,000 Hz

Calculating the result: - c = 250,000,000 meters per second (m/s)

Therefore, based on the given values, the speed of light is approximately 250,000,000 meters per second.

Please note that the provided values are assumed to be accurate for the purpose of this calculation. However, it is important to verify the accuracy of the measurements and consider any potential uncertainties or limitations in the experimental setup.
