Answer:
Option d is correct option = Frequency of light is 6.56×10⁻² Hz
Explanation:
Given data:
Frequency of light = ?
wavelength of light = 4.57×10⁹m
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
f = c/λ
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
f = 3×10⁸ m/s / 4.57×10⁹m
f = 0.656×10⁻¹s⁻¹
s⁻¹ = Hz
f = 0.656×10⁻¹ Hz or 6.56×10⁻² Hz
Mass and weight are the 2 main characters of matter
