1.Why is it necessary to calibrate the spectroscope?
2.Explain how the spectroscope will be calibrated.
3.What is the connection between the flame tests in Activity 1 and fireworks? List 4 metals usedin fireworks and state the color they produce.
Data and ObservationsDue on Canvas before your next in-person lab period (October 12th - 16th)Record all data using the significant figures allowed by the measuring device.

that is not very bright but still noticeable on the spectrum. The yellow, green, and purple lines arewide and sharp in color. The purple line seems to measure to about 4.51 nanometers with a widthof approximately 0.03 nanometers. The blue line is at 5.08 nanometers and has a width of about0.02 nanometers. The green line measures to 5.6 nanometers and has a width of 0.09nanometers. The yellow line measures to 5.9 nanometers and has a width of about 0.1nanometer.Substance:KryptonDescribe the appearance of the spectrum (# of lines, colors, width of the lines, sharpness, etc.)
