Question

How are the different parts of the electromagnetic spectrum arranged accordingly from left to right?

a) increasing wavelength and decreasing frequency

b) decreasing wavelength and increasing frequency

c) increasing wavelength and increasing frequency

d) decreasing wavelength and decreasing frequency​

Answer 1

Answer:

which standard 10th?????

Answer 2

In the electromagnetic spectrum, from left to right wavelength decreases, and frequency increases. Hence, option (b) is correct.

• The wavelength of radio waves is $10^{3} m$ whereas the wavelength of the Gamma rays is $10^{-12} m$. So, you can clearly see the wavelength is decreasing.
• The frequency of radio waves is $3 * 10^{11} Hz$ whereas the frequency of the Gamma rays is ranging between $10^{20} Hz$  and $10^{24} Hz$. So, you can clearly see frequency is increasing from left to right. Hence, option(b) is the correct answer.
