Answer 1

Note that number of letters that should come in a particular Across/Down is not given, so the answers are provided here which should help in filling the crossword. The spellings (for example UV or ultraviolet) and word can differ according to the puzzle given.

ACROSS:

1. Spectrum of the specific wavelengths at which compounds absorb is called absorption spectrum.

3. In Beer Lambert’s Law concentration (of the chemical substance) is proportional to absorbance.

4. Spectrum with wavelength lower than 340nm is in Ultraviolet (UV) region, therefore UV spectra.

9. The detector in a spectrometer captures light and outputs an electrical signal.

10. Where a specific factor is not known, the concentration of a sample can be determined through constructing a Calibration or standard curve by measuring the Absorbance of standards that contain known concentrations of the analyte.

Note that absorbance is taken on y-axis and concentration is taken on x-axis.

DOWN:

2. A graph showing how light from a sample source varies with wavelength is Absorption spectrum

5. Spectrum with wavelength higher than 750 nm is in Infrared (IR) region, so IR spectra.

6. In Beer Lambert’s Law e is the absorptivity or extinction COEFFICIENT.

7. Cuvette (which is a transparent tube inside the sample compartment) is designed to hold samples for spectroscopic experiments

8. Spectrum with wavelength in range of 340 - 750 nm is in the visible region, so visible spectra.
