Question:medium

The waves emitted when a metal target is bombarded with high energy electrons are:

Show Hint

When high
energy electrons bombard a metal target, the emitted radiation is typically \textbf{X
rays}, which result from transitions of electrons in the metal atoms.

  • Microwaves
  • X rays
  • Infrared rays
  • Radio waves
Show Solution

The Correct Option is B

Solution and Explanation

Step 1: Phenomenon Explanation
High-energy electrons impacting a metal target transfer energy to the metal atoms. This energy dislodges inner shell electrons. As electrons from higher energy levels descend to fill these gaps, they release energy as electromagnetic radiation. 
Step 2: Radiation Type Identification 
The energy emitted during this process is typically in the form of X rays. X rays possess significantly higher energy than visible light and are part of the electromagnetic spectrum. 
Radiation types such as microwaves, infrared rays, and radio waves have lower energy than X rays and are not generated by this phenomenon. 

Final Answer: The correct answer is \( X rays .\)

Read the passage carefully and choose the best answer to each question out of the four alternatives.
“People very often complain that poverty is a great evil and that it is not possible to be happy unless one has a lot of money. Actually, this is not necessarily true. Even a poor man, living in a small hut with none of the comforts and luxuries of life, may be quite contented with his lot and achieve a measure of happiness. On the other hand, a very rich man, living in a palace and enjoying everything that money can buy, may still be miserable, if, for example, he does not enjoy good health or his only son has taken to evil ways. Apart from this, he may have a lot of business worries which keep him on tenterhooks most of the time. There is a limit to what money can buy and there are many things which are necessary for a man’s happiness and which money cannot procure. Real happiness is a matter of the right attitude and the capacity of being contented with whatever you have is the most important ingredient of this attitude.”
