$Optics Basics: Refraction Questions! Trivia Quiz - Quiz$

Below are optics basics: refraction questions! Refraction is the bending of a light or sound wave and one of the best examples of refraction taking place is how the rain falls and sunrays form a rainbow. Do you know how this phenomenon is explained and differences that it occurs. The quiz below is perfect for testing out how well you understand refraction, do take it up and see how good you will do!

Questions and Answers

1.

$Refraction is when waves speed up or slow down due to traveling in a different ___________. This is something that waves will travel through. - ProProfs$

Refraction is when waves speed up or slow down due to traveling in a different ___________. This is something that waves will travel through.

Explanation
Refraction is the phenomenon where waves change their speed when they travel from one medium to another. This change in speed is due to the waves traveling through a different medium, which is the substance or material that the waves pass through.

2.

If a medium has more stuff it in (more atoms and molecules), it will move _____________.

Explanation
The given correct answer is "slower" or "Slower". This is because when a medium has more atoms and molecules, there are more particles for the energy to interact with, causing the movement of the medium to be slower. The increased number of particles leads to more collisions and interactions, which slows down the overall motion of the medium.

3.

The two mediums in this example are air and ____________.

Explanation
The question is asking for the other medium besides air in the given example. The correct answer is "water" or "Water". This suggests that the example involves the transmission of something through both air and water.

In air light travels in a __________ line.

Explanation
Light travels in a straight line in air because air is a transparent medium with a uniform refractive index. This means that light rays do not scatter or bend significantly when passing through air, allowing them to travel in a straight path. This property of light is essential for various optical phenomena and is the reason why we can see objects clearly in the air.

5.

When light enters another material it seems to _______________.

Explanation
When light enters another material, it undergoes a change in direction. This change in direction is known as bending.

6.

The bending or change in direction of light when it travels from one medium into another. The __________ bends the light more.

Explanation
The bending or change in direction of light when it travels from one medium into another is known as refraction. The amount of refraction depends on the properties of the medium through which the light is passing. In this case, syrup is the medium that bends the light more compared to the other options given.

$The angle between the refracted ray and the normal is the angle of ___________. - ProProfs$

The angle between the refracted ray and the normal is the angle of ___________.

Explanation
The angle between the refracted ray and the normal is known as the angle of refraction. Refraction occurs when a ray of light passes from one medium to another medium with a different refractive index, causing the ray to change direction. The angle of refraction is determined by the angle at which the ray of light enters the second medium and the refractive indices of the two mediums.

Light bends ____________ from the normal when the speed of light in the 2nd medium is greater than the speed of light in the 1st medium.

Explanation
When the speed of light in the second medium is greater than the speed of light in the first medium, light bends away from the normal. This is known as refraction.

9.

Light bends _________ the normal when the speed of light in the 2nd medium is less than the speed of light in the 1st medium.

Explanation
When light travels from one medium to another, it changes its speed. If the speed of light in the second medium is less than the speed in the first medium, the light will bend towards the normal. This is due to the change in the refractive index of the medium, causing the light to change direction. The three different variations of "towards" in the answer options simply represent different ways of writing the same word.

$The ____________ _____________ is how deep we think the object is due to refraction. - ProProfs$

The ____________ _____________ is how deep we think the object is due to refraction.

Explanation
The apparent depth is how deep we think the object is due to refraction. Refraction occurs when light passes through a medium with a different optical density, causing the light rays to change direction. This change in direction can make an object appear to be at a different depth than it actually is.
