Question

I’m not good at chemistry

Answer 1

Answer:

λ = 5.56 × 10⁻³ m

Explanation:

You have to use the formula c = λv to solve the problem.  Review what you are given.  You are given v and c, where v = 5.40 × 10¹⁰ Hz and c = 3.00 × 10⁸ m/s.  The value c is for the speed of light and is something you need to memorize.  You will use it often in physics and sometimes in chemistry.

Now that you figured out what you know, you can see that there is only one unknown, allowing you to solve.

c = λv

λ = c/v

λ = (3.00 × 10⁸ m/s)/(5.40 × 10¹⁰ Hz)

λ = 5.56 × 10⁻³ m
