Explanation: For an open ended tube,at both the ends antinodes are present,so for #1# st harmonic it's length #l# is equals to distance between two antinodes i.e #lambda/2# where, #lambda# is the …

Given fundamental frequency of standing wave formed n=202Hz Velocity of sound , we know v=343.4m/s Again we have the relationship Wave length lambda =v/n=343.4/202=1.7m Length of the …

De Broglie formalized the prediction in the 1920s - the theory of wave-particle duality. There were contributions and thoughts on the subject prior to this. One example is Einstein who thought about …

The difference is not completely clear-cut. A reagent is a substance added to a system to cause a chemical reaction. It is often dissolved in a solvent before it is added as a solution to the reaction …

Quantization of any physical quantity is that it can only take some discrete values and not continuous values. Example - Quantization of electric charge means that all charges in nature are integral …

a) The average velocity vavg in time interval 1 is zero because he is standing still. In time interval 2, it is 2.02 m/s because that was his constant speed. To calculate the distance he walked, we first need …

No you can't. Unless one of the functions is a constant function. Counter-example: int_0^1 (2x-2) dx = -1 int_0^1 (3x^2+4) dx = 5 int_0^1 (2x-2)(3x^2+4) dx = -4.5 Second counter-example int_a^b x^2 dx != …

This is an interesting and almost philosophical question. (I was hoping someone else would try to answer it first). With the qualification that different environments may have their own standards (for …

We know the relation v=nxxlambda Where n->"frequency of wave" lambda->"wave length of wave" v->"velicity of wave" Velocity of wave being constant we can say …

The effect of strong base on water is to dramatically increase the concentration of OH^- ions and decrease the concentration of H_3O^+ ions. Water always contains at least small concentrations of …
