    Difference between architecture and civil engineering:

     Here I am discussing major differences between architecture and civil engineering, they are as follows:

    1) When we talk about duration of course, then

    • Civil engineering- 4 years
    • Architecture- 5 years

    2) Responsibility:

    •  civil engineer: construction of road bridges and tunnels buildings Railway’s airport’s underpasses, etc.
    • Architect: design buildings, monuments, bridges with a more aesthetical view.

    3) Most important parameter:

    • Civil engineer: the strength of the structure is a more important aspect for civil engineer
    • Architect: an architect give more importance to an aesthetical appearance of the structure

    4) Eligibility criteria:

    • Civil engineering: HSC (physics, chemistry and maths subject) with at least 50% marks and IIT, AIEEE and other university level entrance examinations are conducted each year for the admission of civil engineering course.
    • Architecture: HSC( physics, chemistry, math) with at least 50% marks and NATA, AIEEE and other university level entrance examinations are conducted for admission to architecture course.

    5) Focused Area:

    • Civil engineering- civil engineering field is mainly dealing with the mathematical and scientific aspects of the structure. construction and design, parameters are included in civil engineering
    • Architecture- architecture deals with the down look and artistic aspect of designing a building

    Here, consider lens or mirror at the origin. Now, all the distances measured in the direction of incident rays are positive and distances measured in the direction opposite to the direction of incident rays are negative. All distances have to be measured from the lens or mirror. For example object distance measured from lens or mirror is measured in the direction opposite to direction of incident rays hence, in these case object distance u is negative. The paraxial parallel rays are focused on the right hand side of convex lens. See, this distance f is measured in the direction of incident rays . Hence, focal length of convex lens is positive. But, we can see that focal length of concave mirror is negative. It’s radius of curvature is also negative. The radius of curvature of first surface of convex lens is positive, but radius of curvature of it’s second surface is negative. You can see that radius of curvature and focal length of concave mirror are negative.
