Which plate is covering most of two continents ? what two continents?

Answers

The plate that is covering most of the two continents is the Eurasian plate.
The continents are
1. Europe
2. Asia
The Eurasian plate is a tectonic plate that amasses the whole continent of what others call as “Eruasia”. It takes part of the oceanic crust that starts from the Mid-Atlantic Ridge and extends itself to northward of the Gakkel Ridge. The size of this plate is for about 67,800,000 km according to statistics and geography.

The Eurasian plate covers most of the continents of Europe and Asia.

The frequency of violet light is 7.5x10 to the 14th power hertz. What is the wavelength?

Answers

Wavelength times frequency = speed of light
7.5E14 x wavelength = 300,000 m/s

Wavelength in meters = 300,000 divided by 7.5E14

Final answer:

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.

Explanation:

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.
