The Absorption To Energy Calculator helps you determine the amount of energy absorbed by a substance when exposed to radiation. This is particularly useful in fields such as physics, chemistry, and material science. By inputting either the frequency or wavelength of the radiation, the calculator computes the energy absorbed, aiding in various analyses and experiments.
Formula of Absorption To Energy Calculator
The energy absorbed by a substance can be calculated using the following formula:
E = h * nu
Where:
- E is the energy absorbed (in joules, J)
- h is Planck’s constant (6.626 x 10^-34 J * s)
- nu is the frequency of the radiation (in hertz, Hz)
Alternatively, if you have the wavelength (lambda) of the radiation, the frequency can be calculated using the speed of light (c):
nu = c / lambda
Where:
- c is the speed of light (3 x 10^8 m/s)
- lambda is the wavelength (in meters, m)
So, the energy can also be expressed as:
E = h * c / lambda
This allows you to calculate the energy absorbed based on either the frequency or the wavelength of the radiation.
General Terms Table
| Term | Definition |
|---|---|
| Planck’s constant (h) | 6.626 x 10^-34 J * s |
| Speed of light (c) | 3 x 10^8 m/s |
| Frequency (nu) | Number of cycles per second (Hz) |
| Wavelength (lambda) | Distance between successive peaks (m) |
Example of Absorption To Energy Calculator
Let’s say you want to calculate the energy absorbed by a substance with a radiation frequency of 5 x 10^14 Hz. Using the formula E = h * nu:
E = 6.626 x 10^-34 J * s * 5 x 10^14 Hz
E = 3.313 x 10^-19 J
Therefore, the energy absorbed is 3.313 x 10^-19 joules.
