Answer:
Five professional are Cartographer, Town planner, Teachers, Gis experts, Demographers,
Explanation:
- As cartography is the art and science of making maps the Cartographers use geographic data on maps from various maps, diagrams and define locational boundaries. Use the geographic principles of the globe to form models of the earth's surface.
- Town planners or urban geographers use the art of geography to interpret and plan the cities formation and development, they also use the basic geographic techniques like zoning and land-use patterns of a city, the internal structure, etc.
- Teachers, they use their knowledge of geography to teach and develop approaches so as the student can understand the world better, they use innovative ideas and out of text information to spread this body of knowledge far and wide.
- Demographers, generally study the population parameters based on the statistics and data collected from the surveys both primary and secondary. Population studies also come under this field, and analysis the population age and sex ratio, etc.
- Gis experts or professional working with the software need to have a thorough knowledge of geography as it helps them to formalise and plan various types of maps the as they are governed by the government bodies and private groups in the country.

Explanation:
When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object's material and the frequency (color) of the light. ... However, because light can travel through space, it cannot be a matter wave, like sound or water waves.
When parallel light rays hit a concave mirror they reflect inwards towards a focal point. Each individual ray is still reflecting at the same angle as it hits that small part of the surface. ... Light rays travel towards the mirror in a straight line and are reflected inwards to meet at a point called the focal point. Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.
Also, when light is reflected from a mirror, it bounces off at the same angle in the opposite direction from which it hit. ... If the surface is concave, or curved inward, a group of light rays from a distant source is reflected back toward a single location known as the focal point
