It's simple. You just need to apply formular onto problem.
Answer:
λ = 649 nm
Explanation:
given,
frequency,f = 4.62 x 10¹⁴ Hz
speed of light,c = 3 x 10⁸ m/s
we know,
c = f λ
λ = 6.4935 x 10⁻⁷ m
λ = 649 x 10⁻⁹ m
λ = 649 nm
the wavelength of this light is equal to 649 nm
Explanation:
In this case, it is required to match the following terms with their definitions.
1. Amplitude : the maximum displacement of particles (positive or negative) during wave motion.
2. Crest : the high point of a wave.
3. Frequency : The number of oscillations that occur in a given time period.
4. Hertz : the unit for the frequency of a wave; the number of waves per second.
5. Period : the time required for one wavelength to pass.
6. Stiffness : degree to which a medium resists being compressed.
7. Trough : the low point of a wave.
The above parameters are the characteristics of a wave. A wave is defined by the above parameters. Hence, this is the required solution.
