Final answer:
X-rays and visible light differ in wavelengths and frequencies, with x-rays having shorter wavelengths and higher frequencies, carrying more energy and penetrating matter more deeply.
So, The Correct Option is; they have different wavelengths.
Step-by-step explanation:
The primary difference between x-rays and visible light is that they have different wavelengths. X-rays have shorter wavelengths ranging from 1 × 10-8 to 5 × 10-12 meters and higher frequencies between 3 × 1016 and 6 × 1019 Hz, compared to visible light which has longer wavelengths of 7.5 × 10-7 to 4.0 × 10-7 meters and lower frequencies in the range of 4.0 × 1014 to 7.5 x 1014 Hz.
As a result of this difference in wavelengths and frequencies, x-rays carry more energy and are able to penetrate matter to greater depths than visible light can.
X-rays and visible light differ primarily in their wavelengths. X-rays have shorter wavelengths (1 × 10-8 - 5 × 10-12 m) and higher frequencies (3 × 1016 - 6 × 1019 Hz) compared to visible light (7.5 × 10-7 - 4.0 × 10-7 m; 4.0 × 1014 - 7.5 × 1014 Hz).
Furthermore, X-rays have higher energies due to their higher frequencies. This allows them to penetrate matter to greater depths than visible light.
