Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.

A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
A photodiode is a semiconductor device that converts light into electrical current. It is commonly used in optoelectronic devices such as light sensors, solar cells, and barcode scanners. The function of a photodiode is to detect and measure light intensity by generating a current proportional to the incident light.
One can purchase a photodiode from retail stores like Target, Walmart and many more. One can also purchase a photodiode from online websites like eBay or Amazon.
since the mouse having photodiode installed in them are so fast in response and have less chances of damage.
A light-emitting diode (LED) emits light when an electric current passes through it. A photodiode, on the other hand, generates an electric current when exposed to light. In summary, an LED produces light, while a photodiode detects light.
When Einstein discovered photoelectric effect!
Avalanche photodiode advantages and disadvantagesThe avalanche photodiode has a number of different characteristics to the normal p-n or p-i-n photodiodes, making them more suitable for use in some applications. In view of this it is worth summarising their advantages and disadvantages.. The main advantages of the avalanche photodiode include:Greater level of sensitivityThe disadvantages of the avalanche photodiode include:Much higher operating voltage may be required.Avalanche photodiode produces a much higher level of noise than a p-n photodiodeAvalanche process means that the output is not linear
with a simple led and photo diode
The photodiode's voltage drop varies with the temperature and current flowing through it. The typical voltage drop (VBIAS - VREF) across the MAX4007 series is 0.8V, with a guaranteed maximum of 1.1V.
The Simplest Difference is that LED emits Light, & Photodiode converts Light energy into electrical Energy
A photodiode absorbs sunlight (photons) and converts it to a current (flow of electrons) or a voltage (separation of electrons)
LDRs are switches (when the light hits them they allow electricity to flow if there is a full circuit). So LDRs are different to photodiodes in that way!
A light dependent resistor (LDR) is used for the detection of light.A photodiode is a device that converts light into an electrical current.
