Question

Ultraviolet radiation has wavelengths from 1.0E-8 to 1.0E-7 m, whereas the wavelength region for infrared radiation is 1.0E-6 to 1.0E-3 m. We can say that: 1. The frequency of ultraviolet radiation is ... A. Higher than B. Lower than C. The same as ... infrared radiation. 2. The speed of ultraviolet radiation is ... A. Higher than B. Lower than C. The same as ... infrared radiation

Answer 1

1. A. Higher than

2. C. The same as

Step-by-step explanation:

Wavelength of infrared radiation is more than ultraviolet radiation.

We know that frequency is inversely proportional to wavelength.

`f\propto (1)/(\lambda)`

This means that, the greater the value of wavelength the smaller the the value of frequency will be and vice versa.

So, here the frequency of ultraviolet radiation is higher than infrared radiation.

Speed of radiation of electromagnetic wave is constant irrespective of the wavelength and frequency it posses.

So, the speed of ultraviolet radiation is the same as infrared radiation.
