The refractive index of water is 1.33 a ray is incident from water on air at an angle of incidence equal to 30 degree what is the angle of refraction in air?
nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees
What happens to light as it moves at an angle into a medium that has a lower index of refraction?
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
What happens when light enters an less dense medium at an angle?
When light enters a less dense medium at an angle, it will bend away from the normal (angle of incidence is greater than angle of refraction) due to refraction. This bending occurs because the speed of light changes as it enters a medium with a different refractive index.
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.
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.
What happens if the refraction angle is greater than ninety degrees?
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
If the angle of incidence increases and the indexes of refraction stay the same what happens to the angle of refraction?
The angle if refraction also increases.
What is the incidence angle at which the angle of refraction is 90 degrees called?
A right angle.
Why is the angle of incidence greater than the angle of refraction based on the magic pencil activity?
The angle of incidence is greater.
If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?
The angle of refraction for a beam of light striking a diamond at an angle of 45 degrees will depend on the refractive index of the diamond material. The angle of refraction would be less than 45 degrees due to the bending of light as it enters the denser medium of the diamond.
The refractive index of water is 1.33 a ray is incident from water on air at an angle of incidence equal to 30 degree what is the angle of refraction in air?
nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees nwater * sin 30=nair *sin(angle of refraction) 1.33*0.5=1*sin(angle of refraction) sin(angle of refractiob)=0.665 angle of refraction inair=41.6 degrees
What is a angle called that is over 12 degrees?
An angle greater than 0 but less than 90 degrees is an acute angle An angle of 90 degrees is a right angle An angle greater than 90 but less than 180 degrees is an obtuse angle An angle greater than 180 degrees is a reflex angle
When light is incident on a surface at 30 degrees it is found that reflected ray and refracted ray are perpendicular to each other Find angle of refraction How?
When light is incident on a surface at 30 degrees and the reflected and refracted rays are perpendicular, it means the angles of reflection and refraction add up to 90 degrees (since they are complementary angles). Therefore, the angle of refraction can be calculated as 60 degrees by subtracting the incident angle from 90 degrees. This is based on the principle of Snell's Law, which states that the angle of incidence and angle of refraction are related through the refractive indices of the two mediums.
An angle whose measures is greater then 90?
When the angle = 90 degrees, it is a Right Angle. When the angle is greater than 90 degrees, it is an obtuse angle.
What angle mesures greater than 90 decrease?
An angle greater than 90 degrees is an obtuse angle or a reflex angle if it is greater than 180 degrees
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
What happens to light as it moves at an angle into a medium that has a lower index of refraction?
Light bends away from the normal (angle of incidence < angle of refraction) and travels at a faster speed in the medium with lower index of refraction.
