Answer the Following problems showing all work. Remember, you are solving the problems either using dimensional analysis (DA) or equation method.

Remember 
a. Your constants or conversion factors are c = 3.00E8 m/s or 3.00E8 m Hz, 1 Hz = 1 (1/s), h = 6.60E-34 <nowiki>J/Hz</nowiki> 
b. If you use equations they are c=(lamdha)(f), E=(h)(f) 
c. Write 1/s as one unit over another not a slash 
d. For example, 6.50E-4 m also can be written as 6.50 X 10-4 m 
e. For knowing color, leave blank until I get you a visible light spectrum with wavelength scale
