Consider the following statements about visible light, UV light and X-...
The energy of UV light photons is higher than that of visible light photons, UV light photons. Visible light has a wavelength range from ~400 nm to ~700 nm. Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays. X-rays are a high-energy type of electromagnetic radiation that has a much shorter wavelength than visible light so xray photons have much higher energies than photons of light.

Consider the following statements about visible light, UV light and X-...
Explanation:
Visible light, UV light, and X-rays are all forms of electromagnetic radiation, but they differ in their wavelength and energy. Let's analyze each statement to determine which ones are correct.
1. The wavelength of visible light is more than that of X-rays.
This statement is correct. Visible light has a longer wavelength compared to X-rays. Visible light typically has a wavelength range of approximately 400 to 700 nanometers (nm), while X-rays have much shorter wavelengths, ranging from about 0.01 to 10 nm.
2. The energy of X-ray photons is higher than that of UV light photons.
This statement is correct. The energy of a photon is directly proportional to its frequency, and inversely proportional to its wavelength. Since X-rays have much higher frequencies and shorter wavelengths than UV light, they also have higher energy. X-ray photons can have energies ranging from a few kiloelectron volts (keV) to several hundred keV, while UV light photons typically have energies ranging from a few electron volts (eV) to a few tens of eV.
3. The energy of UV light photons is less than that of visible light photons.
This statement is correct. UV light has higher energy photons compared to visible light. As mentioned earlier, the energy of a photon is proportional to its frequency. UV light has higher frequencies than visible light, so its photons have higher energy.
Therefore, the correct statements are:
- The wavelength of visible light is more than that of X-rays.
- The energy of X-ray photons is higher than that of UV light photons.
Hence, the correct answer is option B: 1 and 2 only.
