It is true that at any given location, the physical properties of a substance do not change.
Answer:Frequency (hz) is some sort of vibration occurs during a particular period of time as either in a sound waves or in an electromagnetic field. Given below an online frequency of light with wavelength calculator to convert from wavelength to hz. Wavelength (λ) is the distance between two waves of energy traveling from one point to another point.
Explanation:
Answer:
B. Infrared.
Explanation:
Referring to the electromagnetic spectrum, ultraviolet rays can be measured with a frequency of 10‐⁸, infrared has a frequency of 10‐⁵, visible radiation has a frequency of 0.5 x 10‐⁶ meanwhile X-rays show a frequency of 10‐¹⁰.
Hence, the largest magnitude among the rest goes to infrared rays, which makes B the correct answer.
Answer:
Who contributed the most to the atomic theory?
After Democritus' discovery, new evidence would be found that would eventually lead to the modern atomic theory. John Dalton, J.J. Thompson, Ernest Rutherford, Niels Bohr, James Chadwick and Ernest Schrodinger each contributed greatly to the modern atomic theory by finding the actual evidence.
