2 part question PLEASE HELP

1. Review the nature of light (section 6.1 in Chemistry, The Central Science, 12 ed). Calculate the frequency of light at 615 nm, the peak of the blue form of HBB. Answer with 3 SF with units of 1/sec, expressed in scientific notation. Do not include units in your answer.

2. Review quantized energy and photons (section 6.2 in Chemistry, The Central Science, 12 ed). Calculate the energy of one photon (one quantum of light) for the frequency of light at 615 nm (the peak of the blue form). Answer in scientific notation with 3 SF and units of Joules. Do not include units in your answer .

Explanation / Answer

Dear Friend your answer should be as follows

= c / to get the frequency:

= (2.99792458×108 m/s) / (615 x 10¯9 m)        since 1 nm = 10¯9 m

= 4.87467411 x 1014 s¯1.

but E = h = (6.62606957×10–34 J·s) (4.87467411 x 1014 s¯1)

E = 3.23 x 10–19 J

Your final answer is :    3.23 x 10–19

Thank You!
