Refraction is when light slightly bends because glass or water is in the way. This makes the object look bent or crooked. For example when you put a straw in a glass of water, the straw looks as if it were bent, but it really isn't. Reflection is when the light particles of an object bounce off of another object showing the same image. You can't see your reflection on all objects though.

What is Refracting and Reflecting?
Reflection: light bounces off of a surface, like a mirror.Refraction: light goes through a substance and bends. For example, white light through a prism comes out in a rainbow because the light is refracted or bent and each color has a different index of refraction.
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45.0 and 8728?
To achieve total internal reflection in a prism, the index of refraction (n) must be greater than the sine of the critical angle. For a critical angle of 45 degrees, the minimum index of refraction can be calculated using ( n = \frac{1}{\sin(45^\circ)} ), which gives ( n = \sqrt{2} ) or approximately 1.414. Therefore, the minimum index of refraction for a glass or plastic prism used in binoculars must be at least 1.414.
Caused by light refraction in the atmosphere?
Mirage is a good example which is seen due to refraction of light and especially due to total internal reflection. ============================ A semi-opposing opinion: No reflection is required for the creation of a mirage, only refraction. ============================= Hope you might have heard about the conditions for total internal relection to take place. 1) Ray has to traverse from denser to rarer 2) the angle of incidence is to be more than critical angle of the denser medium So in such a case the refraction phenomenon cannot take place and so all the energy to be refracted is sent back to the denser medium itself. Hence named as total internal reflection. Of course total internal reflection is totally different from ordinary reflection.
What are the 2 conditions when the direction does not change on refraction?
-- Light approaches the boundary between any two media along the normal direction. -- Light approaches the boundary at any angle and the indexes of refraction of both media are equal.
What is the thinnest film of a thin film with index of refraction n equals 1.38 on glass n equals 1.5 that produces a strong reflection for orange light with a wavelength of 606 nm?
The thinnest film for strong reflection for orange light (606 nm) on glass (n=1.5) with a thin film index of refraction of 1.38 would be approximately 55.8 nm. This can be calculated using the formula for thin film interference: t = (m + 0.5) * λ / (2 * n_film). In this case, the thinnest film would correspond to m=0 (zeroth order reflection).
What does prism do?
A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.

What is the difference from reflection and refraction?
REFLECTION: 1It is the phenomena in which a ray of light after striking a surface retuns back to the same medium. 2.reflection is carried out by the help of mirrors such as concave and convex mirrors. REFRACTION: 1.when a ray of light travels from one medium to another medium its speed changes and this change in speed causes refraction of light. 2.it is caused by lenses such as concace and convex lenses.
What does a prism do with white light?
A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.
2 differences between a mirror and a lens?
A mirror is a device that is based on the principle of reflection whereas lenses are devices that are based on the principle of refraction. They are both used in fields such as optics, astronomy, photography and various other fields.

State the law of refraction?
Ans. The law of reflection states for that: 1. The angle of incidence is equal to the angle of reflection. 2. The incident ray, the reflected ray, and the normal at the point of incidence lie in the same plane.
What is the difference between refraction and transmission?
the difference is transmission occur in same medium,but refraction occurs whn 2 medias are there,its actually bending of light at interface of 2 medias
what is the similarities between cell theory and spontaneous generation?
the similarities is like a 2 sides coin
