Violet light frequency is 7.5 x 10^14 hertz. As according to the relation between light's speed, frequency and wavelength, λ = c / f, the wavelength of violet light can be found to be approximately 400 nanometers.
The relationship between frequency (f), wavelength (λ), and the speed of light (c) is expressed by the equation c = fλ. Given the speed of light c is approximately 3.00 × 10⁸ meters per second (m/s) and the frequency of violet light f is given as 7.5 × 10¹⁴ hertz (Hz), we can solve for wavelength λ. Rearranging the equation gives us λ = c / f. Substituting the given values we find that λ = (3.00 × 10⁸ m/s) / (7.5 × 10¹⁴ Hz), which computes to approximately 400 nanometers (nm). This result corroborates that violet light is typically within the range of 380 - 450 nm, thus confirming its position at the high-frequency, short-wavelength end of the visible light spectrum.

B.mantle convection
C.subduction
D.trench formation
The correct option is (B)mantle convection
Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.
Answer:
2000 Joules
Explanation:
meters away?
Answer:
60m/s
Explanation:
v=s÷t
75m÷1.25s=60m/s
Answer
60
Explanation:
This is because if the question gives you the distance and the time, you have to find the speed.
