Relativity principle:
The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That is, there is no frame which is better (or qualitatively any different) from any other. This principle, along the constancy principle, constitutes the founding principles of special relativity.
What do you mean by Moseley's law? Explain briefly its importance. Explain the origin of X-ray spectra. Describe continuous and characteristic x-ray spectrum.
explain frequency response curve
Sol: The incident angle is 45 because the angle of reflection and angle of incident is equal.
Quality: It is the characteristics of a sound by which we can distinguish among two sounds of the similar pitch and the loudness is known as quality of sound.
