Question

To Which of the following represents the relative order of wavelengths from least

to greatest in the electromagnetic spectrum?
A. ultraviolet light --> violet light ---> red light ---> infrared light
B. infrared light --> red light ---> violet light ---> ultraviolet light
C. violet light --->red light ---> infrared light --> ultraviolet light
D. red light ---> infrared light ---> ultraviolet light --> violet light​

Answer 1

A) ultraviolet light ---> violet light ----> red light-----> infrared light

Step-by-step explanation:

We know that the electromagnetic spectrum with the wavelength from least to greatest is (also refer attachment)

• gamma ray
• X- rays
• Ultra-violet
• Visible

Violet

Indigo

Blue

Green

Yellow

Orange

Red

• Infra-red

• Microwave
• Radio wave

Hence the relative order of wavelengths from least to greatest in the electromagnetic spectrum is

A) ultraviolet light ---> violet light ----> red light-----> infrared light
