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

Answers

Answer 1

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

Wavelength in meters = 300,000 divided by 7.5E14

Answer 2

Answer:

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.

What effect does solar radiation have on climate when comparing the equator to polar- regions?

Answers

Answer:

The solar radiation is one of the main factors that shapes the climate all over the globe, so the climate differs with the less or more solar radiation it gets. The polar regions are cold, this is due to the fact that the solar radiation in here is very obscure, because the solar radiation falls at a very wide angle the heat is dispersed over larger area, thus the land gets very little warmth. The Equator, on the other hand, gets direct solar radiation, the sun light falls at a 90 degrees angle or close to it, so the radiation is more concentrated on a smaller area, thus the warming is bigger.

Answer:

put water at room temperature into a vacuum chamber and begin removing the air. Eventually, the boiling temperature will fall below the water temperature and boiling will begin without heating.

A train moving with a velocity of 87.1 km/hour North, increases its speed with a uniform acceleration of 0.250 m/s2 North until it reaches a velocity of 160.0 km/hour North. What distance did the train travel while it was increasing its velocity, in units of meters?

Answers

Answer:

2780 meters

Explanation:

First, convert km/hr to m/s.

87.1 km/hr × (1000 m / km) × (1 hr / 3600 s) = 24.2 m/s

160.0 km/hr × (1000 m / km) × (1 hr / 3600 s) = 44.4 m/s

Given:

v₀ = 24.2 m/s

v = 44.4 m/s

a = 0.250 m/s²

Find: x

v² = v₀² + 2a (x − x₀)

(44.4 m/s)² = (24.2 m/s)² + 2(0.250 m/s²) (x − 0 m)

x = 2780 m

What is the frequency of light with a wavelength of 6.33x10^-7m

Answers

Answer:

$4.74\cdot 10^(14)Hz$

Explanation:

The frequency of an electromagnetic wave is given by

$f=(c)/(\lambda)$

where

$c=3.0\cdot 10^8 m/s$ is the speed of light

$\lambda$ is the wavelength

For the light wave in this problem, the wavelength is

$\lambda=6.33\cdot 10^(-7)m$

So by using the equation above, we find its frequency:

$f=(3\cdot 10^8 m/s)/(6.33\cdot 10^(-7) m)=4.74\cdot 10^(14)Hz$

Final answer:

The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.

Explanation:

When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:

f = (3.00 x 10⁸ m/s) ÷ (6.33 x 10^-7 m)

By calculating the above equation, you will find the frequency of the light with the given wavelength.

To calculate power, divide the amount of energy transferred by...?

Answers

Fairly simple...the answer is time.

Power, as you should have learned in your class, is a rate; it needs to be multiplied by time to get the amount of energy

Thus, your answer...time.

To calculate power, divide the amount of energy transferred by time.

Final answer:

Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.

Explanation:

In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.
