Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Gamma rays | (i) Emitted from heavy atoms |
| (b) X-rays | (ii) Produced by accelerating electrons in a circuit |
| (c) Radio waves | (iii) Wavelength of 10 –14 m to 10 –15 m |
| (d) Electromagnetic waves | (iv) Travel through vacuum with the same speed |
a-iii, b-i, c-ii, d-iv
a-i, b-ii, c-iii, d-iv
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
Gamma rays are characterized by their very short wavelengths of about 10 –14 m to 10 –15 m and typically originate from atomic nuclei. X-rays are emitted from heavy atoms, while radio waves are produced by accelerating electrons in a circuit. All electromagnetic waves travel through vacuum with the same speed.
