Question

what will be the altitude of sun at 22 December at the
(1)Equator
(2)Arctic Circle
(3)Antarctic Circle
(4)Tropic of Cancer​

Answer 1

Explanation:

Six months later, on December 22 or 23, the autumnal equinox has come and gone and the winter solstice arrives. On this day, the first day of winter and the so-called "shortest day of the year," the situation from summer is reversed, and the sun only reaches an altitude of (90 - 42.36 - 23.5) degrees, or 24.1 degrees.

Answer 2

Explanation:

22nd December is the day of Winter solstice when the southern hemisphere experience the longest day and shortest night.

We have to find the Sun's altitude on this day, which we can find by using a formula:

• Altitude = 90° - Latitude +/- Declination

(Here, Declination is subtracted or added accoro because it is a winter solstice in the Southern hemisphere.$)$

Let's start solving....

(1) Equator (0° N)

⇛ Altitude of sun = 90° - 0° - 23.5°

⇛ Altitude of sun = 66.5°

(2) Artic circle (66.5° N)

⇛ Altitude of sun = 90° - 66.5° - 23.5°

⇛ Altitude of sun = 0°

(3) Antarctic circle (66.5° S)

⇛ Altitude of sun = 90° - 66.5° + 23.5°

⇛ Altitude of sun = 113.5° - 66.5°

⇛ Altitude of sun = 47°

(4) Tropic of Cancer (23.5° N)

⇛ Altitude of sun = 90° - 23.5° - 23.5°

⇛ Altitude of sun = 90° - 47°

⇛ Altitude of sun = 43°

And we are done !!
