Which of the following radiations of electromagnetic waves has the highest wavelength ?
- A UV-rays
- B IR-rays
- C Microwaves
- D X-rays
Answer & Solution
Correct Answer
(C) Microwaves
Step-by-step Solution
Detailed explanation
Increasing order of wavelength of given electromagnetic wave is given as
\(\lambda_{\text {x-rays }} < \lambda_{\text {UV-rays }} < \lambda_{\mathrm{IR}_{\text {-rays }}} < \lambda_{\text {microwaves }}\)
Hence, microwaves has highest wavelengths.
\(\lambda_{\text {x-rays }} < \lambda_{\text {UV-rays }} < \lambda_{\mathrm{IR}_{\text {-rays }}} < \lambda_{\text {microwaves }}\)
Hence, microwaves has highest wavelengths.
