General Science (Easy) Physics

The X-Rays and Gamma Rays are similar to each other in which of the following respects?

1. They have almost similar wavelengths

2. They have almost similar penetrating capacity

3. They are electromagnetic waves

4. They travel with speed of light

Both are ionizing in nature

Select the correct option from the codes given below:

Only 2, 3, 4 & 5

Only 3, 4, 5

Only 1, 2 & 3

Only 3 & 4

Only codes 3,4&5 are corect.

The wavelength of X-rays is of the order of 1Å, whereas wavelength of Gamma-rays is of the order of 10–3Å. ?Both are electromagnetic waves.
X-rays and gamma rays have the same basic properties but come from different parts of the atom. X-rays are emitted from processes outside the nucleus, but gamma rays originate inside the nucleus. They also are generally lower in energy and, therefore less penetrating than gamma rays.
Not all electromagnetic (EM) radiation is ionizing. Only the high frequency portion of the electromagnetic spectrum, which includes X rays and gamma rays, is ionizing.
Since all EM radiations travel at the same speed, X-rays, gamma rays and microwaves will travel at same speed. Since every EM radiations have different wavelengths according to their energy level, X-rays, gamma rays and microwaves will have different wavelengths.
Both travel with the speed of 3 × 108 ms–1.

Hence option 2nd is correct.
