Question

Arrange the following in increasing order of their wavelength.
A. gamma radiations
B. X rays
C. UV radiations
D. microwave
E. Infrared radiations

• A. E, D, C, B, A
• B. B, A, C, D, E
• C. A, B, C, E, D
• D. A, B, C, D, E

Hint:

A mnemonic for the EM spectrum in order of increasing wavelength is: "Good Xylophones Use Very Interesting Musical Rhythms" (Gamma, X-ray, UV, Visible, Infrared, Microwave, Radio).

Answer 1

The Correct Option is C

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.
