Which of the following is the relatively most accurate method for dating of fossils?
Options
- Aradio-carbon method
- Bpotassium-argon method
- Celectron-spin resonance method
- Duranium-lead method.
Correct answer
C. electron-spin resonance method
Step-by-step solution
Electron spin resonance method is relatively most accurate method for dating fossils.
Electron spin resonance dating is a technique that can directly detect unpaired or odd electrons in atomic or molecular systems. In this technique, a static magnetic field and microwaves are used to observe the behavior of the unpaired electrons in the material being studied. The study of the behavior of the electrons in a sample gives information about the condition of the sample.
