Light emitted by element X passes through a diffraction grating having 1200 lines/mm. The diffraction pattern is observed on a screen 75.0 cm behind the grating. Bright fringes are seen on the sceen at distances of 56.2 cm,65.9 cm, and 93.5 cm from the central maximum. What are wavelegths of light emitted by the unknown element?

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the maxium height is 34m/s

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
