Final answer:
We can see objects due to specular and diffuse reflections. Specular reflection occurs on smooth surfaces like mirrors, obeying the law of reflection, while diffuse reflection occurs on rough surfaces, scattering light in many directions. Telescopes utilize these reflections to form images of celestial objects.
Step-by-step explanation:
The type of reflection that enables us to see objects is primarily specular reflection and diffuse reflection. Specular reflection occurs when light reflects off smooth surfaces, such as mirrors, at specific angles corresponding to the law of reflection. This law states that the angle of incidence is equal to the angle of reflection, both measured relative to the perpendicular to the surface where the light ray strikes.
On the other hand, diffuse reflection happens when light reflects off rough surfaces, like paper or clothing, in many different directions. This scattered light allows us to see these objects from various angles. Optical instruments, like telescopes and eyeglasses, utilize these reflections by combining curved mirrors and glass lenses to form images, magnify, or correct vision.
Astronomical telescopes, which allow us to see distant stars and other celestial objects, depend almost entirely on reflective mirrors to form images. The decoding of light and understanding its behavior, such as reflection and refraction, is critical for the function and construction of various optical devices. By exploiting the properties of reflection, we can see objects at great distances and with greater detail.
