Calculate the wavelength in nm of ultraviolet light with frequency of 5.5 x 10¹⁵ Hz.
snow_tiger [21]

Answer: Wavelength of ultraviolet light is 54 nm.

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light.

The relationship between wavelength and frequency of the wave follows the equation:

\nu=\frac{c}{\lambda}

where,

\nu = frequency of the wave  =5.5\times 10^{15}Hz

c = speed of light  =3\times 10^8ms^{-1}

\lambda = wavelength of the wave  

Putting in the values we get:

5.5\times 10^{15}s^{-1}=\frac{3\times 10^8ms^{-1}}{\lambda}

\lambda=0.54\times 10^{-7}m

1nm=10^{-9}m

\lambda=54nm

Thus wavelength of ultraviolet light is 54 nm.

Whitepunk [10]
First, we have to know that the supply chain's stages include first, the customers and he is the main controller of the supply chain. Then, retailers, distributors (who fill the stock of the retailers and at the end the manufacturer's companies.

So when the customer starts to buy the product this represents the final stage of delivering the product to the end of the supply chain and the beginning of collecting information regarding the customer purchase.

When the customer purchases the product, the money and the information will move towards the retailer.
The retailer requests a new order to fill his stock again from the distributor and that makes money and information move towards the distributor.
The distributor requests a new order from the manufacturer's companies so, the money and the information move towards the manufacturer's companies and shipping companies.
So the Customer's purchase is the most powerful stage in the supply chain.
