The longest wavelength of electromagnetic radiation that the sensor can detect is 730 nm.
<h3><u>
What are electromagnetic radiations?</u></h3>
- The electromagnetic (EM) field's waves, which are travelling through space and carrying electromagnetic radiant energy, make up electromagnetic radiation (EMR).
- It consists of X-rays, gamma rays, microwaves, infrared, visible light, ultraviolet, and radio waves.
- These waves are all a component of the electromagnetic spectrum.
- Electromagnetic waves, which are synchronized oscillations of the electric and magnetic fields, are the traditional form of electromagnetic radiation.
- Due to the periodic alteration of the electric or magnetic field, electromagnetic radiation or waves are produced.
- Different wavelengths of the electromagnetic spectrum are created depending on the manner in which this periodic change takes place and the power generated.
Electromagnetic waves move at the speed of light, typically abbreviated as c, in a vacuum.

Solution :
<u>Fieldwork as a Social Science</u>
- Anthropologists use some techniques like interviews, life histories, and mapping.
- Fieldwork is an experiment for testing hypotheses and building theories about human behavior
<u>Fieldwork as an Art</u>
- Fieldwork often sparks mutual transformation for both anthropologist and research participants.
- Anthropologists use their intuition to negotiate complex interactions.
A class member function that automatically initializes the data members of a class is called a constructor.
<h3>What do you mean by constructor?</h3>
- In object-oriented programming, a constructor is a particular method of a class or structure that initializes a newly formed object of that kind. The constructor is always invoked when an object is created.
- Main obj = new Main(); In this case, the Main() constructor is invoked when the object is created. Additionally, the name variable's value is initialized. As a result, the program prints Programiz as the value of the name variables.
- The name of the constructor frequently matches that of the declaring class. They must initialize the object's data members and establish the class invariant, failing if the invariant is incorrect. A well-written constructor's outcome is an object in a usable state.
- When an object of a class is created in C++, the member functions called constructors are called. In C++, constructors fall into one of three categories: default, parameterized, or copy.
