This biconvex disc serves as a refracting medium, keeping the viewed object in focus on the retina. this structure is called <u>Lens</u>.
The fluids and obvious tissues of the attention that refract mild rays passing via them in the direction of the retina: the cornea, aqueous humor, lens, and vitreous humor.
When a mild ray enters a refracting medium, it's far determined that the significance of the attitude of refraction is identical to 1/2 the perspective of reflection.
Dielectric, interface, and glass are substances that transmit and replicate mild specularly, and also manage refraction. The primary two are used for limitations of volumes which might be meant to symbolize strong gadgets of the refracting medium.

Answer:
Naturalistic observation, interviews, and case studies
Explanation:
Three of the most common research methods are naturalistic observation, interviews, and case studies. Each one of them brings something different to the table:
- Naturalistic observation refers to studying subjects directly on their environment without any intervention from the researcher. This is a great method because watching people behave in a natural way will be very revealing and more truthful. When subjects know they are being observed, they often change their behaviour. Naturalistic observation thus requires the observer to be as anonymous and invisible as possible.
- An interview is a research method where the subject is asked to answer to some specific questions crafted by the researcher. Interviews allow the researchers have a much closer look at the subject, trying to ascertain the motives behind their behaviour. However, a problem with interviews is that the subjects often time won't respond truthfully, but will adjust their answers to what is expected from them.
- A case study is a method that goes more in depth than the other two, and the researcher tries to learn as much as possible about the subject through a variety of other methods, like observations, interviews, surveys, etc. Case studies are much thorough and deeper investigations, but they can be very time consuming, and require a subject that is willing to facilitate the work of the researcher, which isn't always possible.
