Arrange the following in increasing order of their wavelength.
A. gamma radiations
B. X rays
C. UV radiations
D. microwave
E. Infrared radiations
A. gamma radiations
B. X rays
C. UV radiations
D. microwave
E. Infrared radiations
Show Hint
- E, D, C, B, A
- B, A, C, D, E
- A, B, C, E, D
- A, B, C, D, E
The Correct Option is C
Solution and Explanation
Step 1: Recall the electromagnetic spectrum.
The electromagnetic spectrum organizes different types of radiation by wavelength, frequency, and energy. Wavelength and frequency/energy are inversely related (short wavelength = high energy).
Step 2: List the main parts of the spectrum in order of increasing wavelength. The standard order is: Gamma rays \(\rightarrow\) X-rays \(\rightarrow\) Ultraviolet \(\rightarrow\) Visible light \(\rightarrow\) Infrared \(\rightarrow\) Microwaves \(\rightarrow\) Radio waves.
Step 3: Apply this order to the given radiations. 1. gamma radiations (A) - Shortest wavelength 2. X rays (B) 3. UV radiations (C) 4. Infrared radiations (E) 5. microwave (D) - Longest wavelength
Step 4: Form the final sequence. The correct sequence for increasing wavelength is A, B, C, E, D.
