Current Question (ID: 17435)

Question:

$\text{Consider the following statements about electromagnetic waves and choose the correct ones:}$ $\text{S}_1: \text{Electromagnetic waves having wavelengths 1000 times smaller than light waves are called X-rays.}$ $\text{S}_2: \text{Ultraviolet waves are used in the treatment of swollen joints.}$ $\text{S}_3: \text{Alpha and gamma rays are not electromagnetic waves.}$ $\text{S}_4: \text{de-Broglie waves are not electromagnetic in nature.}$ $\text{S}_5: \text{Electromagnetic waves exhibit polarization while sound waves do not.}$

Options:

1. $\text{S}_1, \text{S}_4, \text{and S}_5$
2. $\text{S}_3, \text{S}_4, \text{and S}_5$
3. $\text{S}_1, \text{S}_3, \text{and S}_5$
4. $\text{S}_2, \text{S}_3, \text{and S}_4$

Solution:

$\text{Hint: Recall the properties of em-waves.}$ $\text{Step: Deduce the correct statements.}$ $(1) \text{The wavelength of x-rays is 1000 times smaller than light waves.}$ $(4) \text{de Broglie waves are matter waves}$ $(5) \text{Sound waves do not exhibit polarization.}$
