Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.

Answer:
1.58×10² nm
Explanation:
Given data:
Frequency of light = 1.90 ×10¹⁵ Hz
wavelength of light = ?
Solution:
Speed of light = wavelength × Frequency
Speed of light = 3×10⁸ m/s
3×10⁸ m/s = λ × 1.90 ×10¹⁵ Hz
Hz = s⁻¹
λ = 3×10⁸ m/s / 1.90 ×10¹⁵s⁻¹
λ = 1.58×10⁻⁷ m
meter to nm:
1.58×10⁻⁷ m ×10⁹ nm/ 1m
1.58×10² nm
It’s A or B but liquids take the shape of their container so I bet you it’s B
