Explanation:
γ-rays have the least wavelength:
Gamma rays have the shortest wavelength among the options given. The wavelength of γ-rays is shorter than that of X-rays, β-rays, and α-rays.
γ-rays:
- γ-rays are a form of electromagnetic radiation of high frequency and high energy.
- They have the shortest wavelength and highest frequency among the options given.
- γ-rays are produced by the decay of atomic nuclei and in nuclear reactions.
- They have very high penetrating power and can travel through most materials.
β-rays, α-rays, and X-rays:
- β-rays have longer wavelengths compared to γ-rays but shorter wavelengths compared to α-rays and X-rays.
- α-rays have longer wavelengths compared to γ-rays, β-rays, and X-rays.
- X-rays have longer wavelengths compared to γ-rays, β-rays, and α-rays.
Therefore, among the given options, γ-rays have the least wavelength.
