Explanation:
The correct answer is option 'C' - The speeds of both the photons in vacuum are different.
Reason:
1. The speed of light in vacuum is a universal constant, denoted by 'c', which is approximately equal to 3 x 10^8 meters per second (m/s). It is the maximum speed at which any information or energy can travel in the universe.
2. The speed of light is independent of the wavelength or frequency of the light wave.
3. This means that all photons, regardless of their energy or wavelength, travel at the same speed in vacuum, which is the speed of light.
4. Therefore, the statement that the speeds of both the X-ray photon and visible radiation photon in vacuum are different is incorrect.
Key Points:
- The wavelength of X-ray photon is less than the wavelength of visible radiation photon.
- Both the photons have different energies.
- The frequency of X-ray photon is higher than the frequency of visible radiation photon.
Additional Information:
- X-rays have higher energy and shorter wavelengths than visible radiation.
- X-rays are a form of electromagnetic radiation with wavelengths ranging from 0.01 to 10 nanometers (nm).
- Visible radiation, or visible light, is a subset of electromagnetic radiation with wavelengths ranging from approximately 400 to 700 nm.
- The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength according to the equation E = hf = hc/λ, where E is the energy, h is Planck's constant, f is the frequency, c is the speed of light, and λ is the wavelength.
- X-ray photons have higher energies because they have higher frequencies and shorter wavelengths compared to visible radiation photons.
- The speed of light is a fundamental constant in physics and is the same for all electromagnetic waves, including X-rays and visible radiation.
