∙ 8y agoThe answers for this question were not given. So I have an example the answer choices are 0, 1/4, 5/4, and 1/2. The answer would be 5/4. A simple rule to follow is any value that is greater than 1 can be used. 5/4
it has to be grater than 1.0 so its 1 and one fourth. or 5 over 4.
lol
actually i just took the penn foster test and that's not right. its c. 1/2
the answer can be found on page 12-14 in the penn foster study unit.
5/4
pennF
pg 26 3rd paragrapgh "all materials must have an index of refraction greater than 1.
D) it is the only value greater then 1)) 5/4

∙ 11y agoThe index of refraction in a substance is equal to the speed of light in a vacuum, divided by the speed of light in the substance. For example, an index of refraction of 1.5 in a substance means that the speed of light in such as substance is 300,000 km/sec divided by 1.5, that is, 200,000 km/sec.

Wiki User
∙ 11y agoThere is no Refractive Index for the opaque objects as the opaque objects does not allow the light ray to pass through them.So there won`t be any refraction.

What happen when light is directed at a transparent materials?
When light is directed at transparent materials, it bounces off of the particles and is refracted accordingly. This causes the light to bend according to the materials refraction index. The higher the refraction index of the material, and the thicker it is, the more it bends the light and separates the colors.
What is materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
What is the materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
Why does the incident angle not equal the angle of refraction?
i=incidence angle, r=angle of refraction Refractive index= sini/sinr Since for different materials value of refractive index is different hence both angles are not equal.
Does the wavlength increase when a refraction of a wave occurs when the wave travels from one material into another?
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.

What is the angle or refraction when the angle of incidence is 40degrees?
That depends on the substances where the refraction occurs. The relationship between the angles, and the index of refraction of both materials, is given by Snell's Law.
Why does the incident angle not equal the angle of refraction?
i=incidence angle, r=angle of refraction Refractive index= sini/sinr Since for different materials value of refractive index is different hence both angles are not equal.
Will light bend if it enters a new material?
Yes. It depends on the angle of incidence and the details of refractive index of materials.
Does the wavlength increase when a refraction of a wave occurs when the wave travels from one material into another?
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.
What does refractive index mean?
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
When light passes from a medium with a high index of refraction into a medium with a lower index of refraction which direction does the light bend?
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
What is the physical significance of refractive index?
