Math Is Hard said:A UV photon can break chemical bonds, but an IR photon can only cause vibration in the bonds. Calculate the energy associated with these processes by assuming a wavelength of 320 nm for the UV photon and a wavelength of 5000 nm for the IR photon.
I got...
UV photon: E = 6.22 x 10-19Joules
IR photon: E = 3.98 x 10-20Joules
Thanks!
To calculate energy, you need to know the mass of the object and its speed. The formula for calculating energy is E= 1/2 mv^2, where E is energy, m is mass, and v is velocity.
The unit of energy is joules (J). Other common units of energy include kilojoules (kJ) and calories (cal).
To check your energy calculation, make sure you have correctly plugged in the values into the formula and that you are using the correct units. You can also use an online energy calculator or ask a colleague to double-check your work.
Yes, energy can be negative. This typically occurs when the object is losing energy, such as in a decelerating motion or during energy conversions.
Energy calculation is used in many real-life applications, such as determining the energy needed to power a car, calculating the energy output of a power plant, and measuring the energy efficiency of appliances. It is also used in physics experiments and in understanding the energy transfer in everyday scenarios, such as a ball rolling down a hill.
