Energy of a photon = hc/λ
           3.65 x 10^-19 = 6.626 x 10^-34 x 2.99 x 10^8/λ
                                λ = 6.626 x 10^-34 x 2.99 x 10^8 / 3.65 x 10^ -19
                                   = 5.42 x 10^-7 m.

Hence wavelength of photon is 5.42 x 10^-7 m.

Hope this helps, have a great day/night ahead!

A train travels at a speed of 30 miles per hour. If 1 mile = 1.6 kilometers, how fast is the train traveling in kilometers per m
Alina [70]
The answer 
 the speed of <span>the train traveling in kilometers per minute can be found by using the following method:
v = </span><span>30 miles per hour
</span><span>1 mile = 1.6 kilometers

just do the calculus by changing miles to kilometers
 </span>1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
 so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn  = 0.8 km/ mn
the answer is
<span>C- 0.8 km/min</span>
