Question

Write the following radiations in descending order of frequencies:
red light, X-rays, microwaves, radiowaves.​

Answer 1

Answer:

1. Radiowave=500kHz to 1000MHz, Microwave= 10∧(9) to 10∧(12), X-ray=10∧(16)Hz to 10∧(19)Hz, redlight= 10∧(11)to 10∧(14)Hz

Explanation:

Answer 2

Frequency: X-rays > Red light > Micro waves > radio waves

Explanation:

The x-rays have a frequency of the order of: $10^{17}\ to\ 10^{20}\ Hz$

The red light has a frequency of the order of: $10^{14}\ Hz$

The micro-waves have a frequency of the order of: $10^{11}\ to\ 10^{13}\ Hz$

The radio waves have a frequency less than the order of: $3\times 10^{11}\ Hz$
