Calculate the Wavelength in Nanometers

Introduction:
In the field of physics, the concept of wavelength is crucial for understanding the behavior of waves. Wavelength refers to the distance between two consecutive points in a wave that are in phase with each other. It plays a significant role in determining various wave properties, such as frequency and energy. In this article, we will explore how to calculate the wavelength of a wave in nanometers.

Definition of Wavelength:
Wavelength is defined as the distance between two consecutive points in a wave that are in phase with each other. It is measured in units of length, such as kilometers, meters, or nanometers. The wavelength can be determined by analyzing the pattern of crests and troughs in a wave.

Calculating Wavelength:
To calculate the wavelength of a wave in nanometers, we need to know the wave’s frequency and the speed at which it travels. The formula to calculate wavelength is given by:

Wavelength (in meters) = Speed / Frequency

Once the wavelength is calculated in meters, it can be converted to nanometers by multiplying it by a conversion factor. The conversion factor is 1 meter = 1,000,000,000 nanometers.

Example Calculation:
Let’s consider an electromagnetic wave with a frequency of 5 x 10^14 Hz and a speed of 3 x 10^8 m/s. To calculate the wavelength in nanometers, we will use the formula mentioned above.

Wavelength (in meters) = Speed / Frequency
Wavelength = 3 x 10^8 m/s / (5 x 10^14 Hz)
Wavelength = 6 x 10^-7 meters

Now, let’s convert the wavelength from meters to nanometers using the conversion factor.

Wavelength (in nanometers) = Wavelength (in meters) x Conversion Factor
Wavelength = 6 x 10^-7 meters x 1,000,000,000 nanometers
Wavelength = 600 nanometers
