Cross sectional area of concrete slab?
The cross sectional area of a slab can be found by squaring the height of the slab.
How do you calculate the volume of concrete in a circular slab?
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
How do you calculate the area of a rectangular slab?
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
How many square feet in a slab of granite?
Probably none because a slab of granite would be measured in cubic feet.
What are the types of serifs?
Usually the serif fonts are divided into 2 categories, slab serif and serif. Clarendon is an example of a slab serif.
The incident ray and the emergent ray will always be?
The incident ray and the emergent ray will always be parallel when light passes through a parallel-sided transparent medium like a glass block or a prism.
Why is the emergent ray parallel to direction of the incident ray in a rectangular glass slab?
In a rectangular glass slab, the emergent ray is parallel to the incident ray because of the principle of refraction. When light enters a denser medium (like glass) from a rarer medium (like air), it bends towards the normal. As the light exits the glass slab and reenters air, it bends away from the normal. The combination of these two refractions results in the emergent ray being parallel to the incident ray.
What is a glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
When a light ray enters a rectangular glass slab at an angle, it bends towards the normal due to refraction. As it exits the glass slab, it bends away from the normal by the same amount due to refraction again. The angles at which the light ray enters and exits the slab are such that they cancel out the overall deviation, resulting in the emergent ray being parallel to the incident ray.
Is incident ray parallel to the emergent ray through two glass slab of different refractive index?
No, the incident ray and emergent ray will not be parallel if the glass slabs have different refractive indices. This is because the light rays will experience refraction at each interface as they pass through the slabs due to the change in refractive index, causing the emergent ray to be offset from the incident ray.
What is glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.
How can the lateral displacement of the emergent ray with respect to incident ray in glass slab be increased?
The lateral displacement of the emergent ray with respect to the incident ray in a glass slab can be increased by increasing the angle of incidence of the light ray on the surface of the glass slab. This phenomenon is a result of refraction, where the change in angle of the light ray as it enters the glass causes the lateral displacement.
What is the formula for finding the lateral displacement of an incident ray when it passes through a glass slab?
The lateral displacement (D) of an incident ray passing through a glass slab can be calculated using the formula D = t * sin(i - r), where t is the thickness of the glass slab, i is the angle of incidence, and r is the angle of refraction. This formula takes into account the deviation of the ray as it passes through the glass slab.
How should a ray of light be incident on a glass slab so that it comes out from the opposite side of slab without being displaced?
The ray of light should be incident perpendicular to the surface of the glass slab. This ensures that the light ray does not get deviated or displaced while passing through the glass slab, emerging on the other side in the same direction.
What is the angle between incident ray of light and emergent ray of light when incident ray of light falls obliquely?
The angle between the incident ray of light and the emergent ray of light is called the angle of refraction. It is determined by the refractive properties of the medium through which the light is passing, as described by Snell's Law. The angle of refraction depends on the angle of incidence and the refractive indices of the two media involved.
What happens if light is passed through a glass slab whose sides are not parallel?
it becomes kinda prism
What happens when light is perpendicular to glass slab?
When light is perpendicular to a glass slab, it passes through unaffected without any deviation in its path. This phenomenon is known as normal incidence, where the incident light ray and the refracted ray are along the same line.
