Answer:
Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.
Explanation:
Answer:
367.57 nm
Explanation:
Given that the speed of the light in certain material is 0.6310 times the speed of light in vacuum.
Speed of light in vacuum = 3×10⁸ m/s
Speed of the light in that material = 0.6310×3×10⁸ m/s = 1.893×10⁸ m/s
The frequency of the light does not change but the wavelength of the light changes with change in the speed when light travels from one medium to another.
Thus, frequency = 5.15×10¹⁴ Hz
Using,
c = frequency × Wavelength
Wavelength = c / frequency = (1.893×10⁸ m/s) / (5.15×10¹⁴ Hz) = 367.57×10⁻⁹ m
Also,
1 nm = 10⁻⁹ m
<u>So, wavelength = 367.57 nm</u>
