The velocity of light is v = 3 x 10⁸ m/s.
The given wavelength is λ = 0.86 nm = 0.86 x 10⁻⁹ m.
Note that
v = fλ
where f = frequency.
Therefore
f = (3 x 10⁸ m/s)/(0.86 x 10⁻⁹ m)
= 3.488 x 10¹⁴ Hz
Answer: 3.49 x 10¹⁴ Hz
Answer:
huh english plssss bc I didn't understand
Answer:
The Magnitude of the angle of reflection equals that of Incidence from the Law of reflection
So its 50°.
Explanation:
False its really its not true
Answer:
45 N
Explanation:
F= ma (ie force is found by multiplying the mass of the object by its accerelation)
thus, F = 15 X 3 = 45 N
