What is the frequency, in hertz, of an electromagnetic wave with a wavelength of 625 nm?

Chemistry

Reika [66]3 years ago
6 0

Answer:- Frequency is 4.80*10^1^4Hz .

Solution:- The wavelength of electromagnetic radiation is given as 625 nm and we are asked to calculate the frequency. Frequency is inversely proportional to the wavelength and the formula used to calculate frequency when wavelength is given is:

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

where, \nu is frequency, c is speed of light and \lambda is the wavelength.

Value of speed of light is \frac{3.0*10^8m}{s} . We need to convert the given wavelength from nm to m.

1nm=10^-^9m

So, 625nm(\frac{10^-^9m}{1nm})

= 6.25*10^-^7m

Let's plug in the values in the formula and calculate the frequency:

\nu =\frac{3.0*10^8m.s^-^1}{6.25*10^-^7m}

= 4.80*10^1^4s^-^1 or Hz.

So, the frequency of the electromagnetic wave is 4.80*10^1^4Hz .

inna [77]

Answer:

The volume of the gasoline in the tank is 18.85 cubic feet

Explanation:

The tank is a cylinder. The equation for calculating the cylinder volumen is πr²*h, r is radius and h is height. π is approximately 3.1416. So,  The tank is  resting horizontally on its side, its radius is 2 feet/2= 1 feet. h=a tank long= 6 feet.

With equation:

Vol gasoline=3.1416*1²*6=18.85 feet ³
