False. You can have total internal reflection where the effective angle is greater than 90 deg

How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?

Angle of refraction will be less compared to the angle of incidence in this case.


Is it true an acute angle had a measure greater than 90 degree's and less than 180 degree's?

False because an acute angle is greater than 0 and less than 90 degrees


How does the angle of refraction change as the index of refraction of the bottom material increases?

As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.


If angle of incidence equals critical angle what is angle of refraction?

If the angle of incidence equals the critical angle, the angle of refraction would be 90 degrees. This occurs when light travels from a denser medium to a less dense medium and undergoes total internal reflection.


When a beam of light passes at an oblique angle into a material of lower optical density the angle if incidence is what?

less than the angle of refraction.


When a beam of light of passes at an oblique angle into a material of lower optical desity?

less than the angle of refraction


What shape is a 5 degree angle?

A 5 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.


What is the relationship between the prism angle and the refraction of light passing through a prism?

The prism angle affects the amount of refraction of light passing through a prism. A larger prism angle results in greater refraction, causing the light to bend more as it passes through the prism. Conversely, a smaller prism angle leads to less refraction and a smaller bending of the light.


Which angle is less than 90 degree?

An acute angle


An acute triangle is a triangle that has one 90 degree angle true or false?

False. That is a right (-angled) triangle. An acute triangle has all three angles less than 90o


Which is larger the angle of incidence or the angle of refraction why?

The angle of incidence is typically larger than the angle of refraction because light bends towards the normal when it passes from a less dense medium to a more dense medium, causing the angle of refraction to be smaller. This is known as refraction and follows Snell's Law.


What type of angle is 1 degree?

an acute angle, which is an angle less then 90
