Example 1.5

Postby Matthew Leung 1B » Tue Jul 04, 2017 2:57 pm

Just want to make sure that I didn't make wrong calculations for part B. At the bottom of that page, the last step was finding the wavelength by 3.00*10^8 / (5.7*10^-19 / 6.626*10^-34). I got 3.49 * 10^-7 m as opposed to 3.49 * 10^-17 m as stated in the textbook, can anyone help verify this? Thanks!

Yes, you are correct, 3.49*10-7 m!

The textbook's conversion to 349 nm also corresponds.

Does anyone know if 10-9 m and nm will be interchangeable?

Yes they are equivalent to my knowledge!
