Either the answer will be that they contain more solar energy, it strike's the earth at an angle greater than 90 degrees, or it could be that they spread energy over a larger surface area.
Oblique incidence applies to rays that are incident at some angle OTHER THAN at right angles (90 degrees) to the surface on which they are incident. Vertical incidence IS at right angles.
they are vertical angles
vertical opposite equal angles
<----.----> <---------. .----------> Those are the Rays in a line, or segment
A side refers to one of the rays that form an angle. Vertical are also called opposite angles. They are nonadjacent angles formed by intersecting lines.
They contain more solar energy!
Obviously the angle of incidence is different. The oblique rays spread their energy over a larger area of the surface than vertical (also called perpendicular or normal rays)
Oblique incidence applies to rays that are incident at some angle OTHER THAN at right angles (90 degrees) to the surface on which they are incident. Vertical incidence IS at right angles.
These two types of rays differ in their Angles of Incidence: vertical rays bounce down and then right back up into themselves while oblique rays bounce off at different angles (vectors) from the incident angle of the incoming rays, also called waves. Compare this to horizontal rays that while sent out side to side, if they do not hit a mountain range, they will wave away indefinitely forever.
Because vertical solar rays are less oblique during Sumner and are concentrated over smaller areas
This is a result of the tilt of the Earth's axis. This causes 3 different kinds of rays: tangent, oblique, and direct.
Oblique is defined as 'slanting or inclined in direction, neither parallel nor perpendicular'. Oblique rays, such as those that come from the sun during winter, tend to bounce away more than they are absorbed, due to being shot at a wide angle.
Oblique.
Southern India lies in the equatorial belt. It receives almost vertical rays from the sun throughout april. These rays have a greater heating effect than oblique rays. Hence, south India is very hot in the month of April.
Only between 23.5 degrees on each side of the equator. The earth is tilted at 23.5 degrees, so the sun's vertical rays will only oscillate between those latitudes throughout the year. They are at those extremes during the solstices.
Oblique rays that strike the object. Oblique rays strike the object being viewed, illuminating the object and reflect light rays up through the objective.
