Question
Chapter 27, Problem 28A
To determine
The shorter wavelength & higher frequency among ultra-violet or infrared waves.
Expert Solution & Answer
Answer to Problem 28A
The shorter wavelength of ultra- violet waves & ultra-violet has higher frequency.
Explanation of Solution
Introduction : The wavelength is reciprocal of frequency.
The ultra-violet has shorter wavelength than the infrared .As the frequency is reciprocal of wavelength, so the frequency of ultraviolet is higher than the infrared waves .
Conclusion:
The shortest wavelength & higher frequency is of ultra-violet waves.

The bimetallic Pt-Ni nanoparticles are expected to decorate on the side surfaces of the aligned TiO2 nanorod arrays. These aligned TiO2 nanoarrays grew on the flat SiO2 monolith. Let's assume that the sizes of the Pt-Ni nanoparticles are > 10 nm.
