Answer:
f = 8×10¹⁴ s
Explanation:
λ × f = c ⇒ f = c/λ
(c = speed of light [3×10⁸ m/s])
(λ = wavelength)
1. Convert 375 nm to meters in order to multiply by speed of light unit (m/s)
375 nm × [tex]\frac{1 meter}{10 ^{9} nm}[/tex] = 3.75 × 10⁻⁷ m
2. Plug in converted wavelength to top equation
f = (3×10⁸ m/s)/(3.75 × 10⁻⁷ m)
f = 8×10¹⁴ s
