Pitch is the frequency at which an object vibrates to create a sound. A tuning fork, for example, that vibrates 440 times a second will produce a perfect "A" note. It is these predetermined levels of frequencies that pitch is categorized into the twelve chromatic musical tones.
No, a perfect vacuum has not been made.
In the perfect specular, the reflected ray is determined by the angle the incident ray makes with the surface normal. which means it is fully predictable. In the near perfect, the reflected ray will be near the same of the perfect, but not the same. In a difuse reflection, the ray is far from being equal to the perfect specular.
The thermal conductivity of a perfect conductor is 1
Perhaps if either:The length of the pendulum is infiniteThe pendulum is in perfect zero gravity and has no momentumBut in each of those cases, does it really qualify as a pendulum?

It depends of how much you wanna spend... Flat frequency response everywhere in the room. and perfect stereo imaging everywhere. good luck

A good material for an antenna is copper wire. For perfect reception, the antenna should be cut to a length determined by the frequency you want to receive. length = 468/frequency in megahertz.
energy is transferred to different forms.
When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.

Yes. In a vacuum, the only resistance is the friction in the suspension for the bob of the pendulum. Other than that, it should swing a long time. In air, friction with air will add to the friction in the suspension and it won't swing as well as it would in a vacuum. But it will swing for a while. A pendulum will swing in water, but the hydrodynamic drag will make it stop in a really, really short period of time. Just a couple of swings will strip the pendulum of almost all its energy. And the speed of the pendulum will be slower than in air, and it won't swing anywhere nearly as far through the bottom of its arc as it did in air.

Grand father , take a rest and medicines. I will visit at there on monday.
