solar calculator
Yes it has.
A solar calculator is powered by photovoltaic cells that convert light into electricity. When exposed to light, these cells generate a current that powers the calculator's functions.

No, the human cannot see ultraviolet rays with the naked eye.
Because when moving at the speed of light, time stops for you and you can no longer measure speed (distance covered in a certain time).
The particle nature of light, as described by the photon theory, cannot be fully explained by the wave model of light. The wave model also cannot account for certain phenomena such as the photoelectric effect and the behavior of light in very small scales, which require a particle-like description of light.
It needs light, such as sun light.

The energy transformation during the operation of a solar calculator is radiant energy to mechanical energy. This is so because radiant energy is light and the sun is light, then it changes to mechanical energy because mechanical means energy is stored in the calculator to operate.
There is a certain volleyball because you cannot use another type of ball, because they are all too heavy or too small, so the volleyball has to be big and light.
Because certain objects can absorb specific wavelengths of light(color) and they reflect the waves that they cannot absorb. the reflected wave of light is the visible color of the object.
A solar power calculator harnesses solar energy from light, which is converted into electrical energy by the solar panel on the calculator. This electrical energy is then used to power the calculator.
