The plane abcd is the base of the cuboid.

Abcd is a plane glass cube. The two planes on opposite sides of a cube are parallel to one another. M n r q p 12cm 20cm 30 l diagram not accurately drawn triangle pqr is a cross section of the prism. 2 a ray of light striking the interface of two media glass and air from glass at an angle of incidence equal to 45 which is greater than the critical angle 42 suffers total internal reflection.

Problem 06 the plane section abcd shown in the figure is cut from a cube of edge a. A ray of light pq is incident normally on the hypotenuse of a right angled prism abc as shown in the diagram given below. In geometry a plane is any flat two dimensional surface.

Parallel planes are found in shapes like cubes which actually has three sets of parallel planes. A x b y c z d 0 ax by cz d 0 a x b y c z d 0 where at least one of the numbers a b a b a b and c c c must be non zero. Two planes that do not intersect are said to be parallel.

In going from a less dens e medium air to a more dense medium glass light bends towards the normal this means that i r the angle i is greater than the angle r. The angle between af and the plane is x. A is a vertex of the cube while b and c are located on opposite edges of the cube with both b and c being 1 inch from the nearest vertex.

The diagram shows a cube of side length 4 inches. As you notice that there are two right triangles in a cube that are parallel to each other. Give your answer correct to 1 decimal place.

We need to solve for their hypotenuse using pythagorean theorem as follows since ad bc ab cd ad bc and ab cd then quadrilateral abcd is a rectangle which is a cutting plane. If a plane including the points a b and c cuts through the cube what is the shape of the resulting cross section. Draw the right angled triangle afc and label the sides.

When a ray of light enters a glass block at an angle other than the normal it changes speed wavelength and direction as shown below. Pr fp mp 12cm angle prq angle pqr calculate the size of the angle that the line mr makes with the plane rqln. A plane in 3d coordinate space is determined by a point and a vector that is perpendicular to the plane.

An isosceles triangle a rectangle a square. Find the area of the section if d and c are each at the midpoint of an edge.
