Why should the wavelength scale of a spectroscope be calibrated?

Is it possible to obtain negative values of the absorbance and in what conditions? In reference to Beer's Law.

What is frequency factor?

Make calibration graph by plotting the known wavelengths versus the recorded line positions on the graph below

Determine the number of RMN-1H signals for the following compunds.

Assuming the antenna of a 10.0-kW radio station radiates spherical electromagnetic waves, (a) compute the maximum value of the magnetic field 5.00 km from the antenna and (b) state how this value compares with the surface magnetic field of the Earth.

Determination of Analytical Wavelength Question: Why is it important to determine λmax and take absorbance readings of the standards and the sample at thiswavelength?

What is threshold frequency?

A reflection diffraction grating has 1294 grooves per mm, and 13.4 mm of illuminated area. What must be the separation (in nm) of two first-order spectral lines centered at 625 nm if they are to be resolved? (Answer should be to 4 decimal places)
