Question

1) What is frequency and wavelength
2) Explain molecular mass

Answer 1

Answer:

1. The peak of the wave. frequency: Is the number of waves that pass a certain point in a specified amount of time. trough: The low point of the wave cycle. wavelength: The distance between two successive peaks.

2.The molecular mass is the mass of a given molecule: it is measured in daltons. Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.
