Answer:
Explanation:
The formula relating the frequency (f) and wavelength (λ) is
fλ = c
1. Convert nanometres to metres
295 nm = 295 × 10⁻⁹ m
2. Calculate the frequency
It is an example of physical change. The molecules are not changing, so it is not chemical, and a physical property is something that a physical thing has.
