Does a black hole have infinite mass?
No, a black hole definitely does not have infinite mass. In some mathematical models, there is an object called a singularity, inside a black hole, which has infinite density. That is not the same as infinite mass. If a finite mass is contained in zero volume, then the density becomes infinite. We do not have any real confirmation that such a thing as a singularity or an infinite density actually exist, but they may.
What is light and heavy hole in semiconductor?
In semiconductors, a light hole and a heavy hole refer to different energy states that are created in the valence band. Light holes have lower effective mass and higher mobility, while heavy holes have higher effective mass and lower mobility. These terms are important in understanding the electronic band structure of semiconductors and their properties.
What is heavy hole light hole and split-off hole?
the occupied highest band is the heavy band, the band prior below it is ligh band, the distance between two extremal points of those band is split-off band. At those points, hole is situated to be corresponding holes.
What is the natural frequency of a material?
The natural frequency of a material is the frequency at which it naturally tends to vibrate when subjected to a disturbance. It is determined by the material's physical properties, such as its stiffness and mass. Natural frequency is an important factor in engineering design to prevent unwanted vibrations and resonances.
If a mass travels at the speed of light does that mass turn into light energy?
No, a mass cannot travel at the speed of light according to Einstein's theory of relativity, as its mass would become infinite which is not physically possible. Photons are particles of light that always travel at the speed of light and have zero rest mass.
Why effective mass of electron is negative at the top of valence band?
The effective mass of an electron in a solid is determined by its curvature of the energy band. At the top of the valence band, where the curvature is negative, the effective mass of the electron is also negative, reflecting the opposite relationship between the momentum and velocity of the electron in this region. This negative effective mass indicates that the electron behaves as if it has a negative charge moving in the opposite direction.
How can one calculate the effective mass of a particle in a solid-state system?
To calculate the effective mass of a particle in a solid-state system, one can use the band structure of the material and apply the concept of curvature in the energy-momentum relationship. This involves determining the second derivative of the energy with respect to momentum at the band extrema, which gives the effective mass of the particle.
How can the effective mass calculation from band structure be utilized to understand the electronic properties of materials?
The effective mass calculation from band structure helps in understanding how electrons move in materials. By determining the effective mass, scientists can predict how electrons will behave in different materials, such as their mobility and conductivity. This information is crucial for designing new materials with specific electronic properties for various applications, like in semiconductors for electronics.

Is it more correct to say that a Black Hole has infinite mass or infinite gravity?
A black hole has infinite density.
Are black holes infinite in size and mass?
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.

How much muscle mass does Ben Affleck have?
infinite.
Is it true holes have a mass?
The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.
