What is the altitude of the Sun for someone in Montreal, Canada (46°N), on December 22? (Enter the altitude of the Sun at noon.)
To calculate the altitude of the Sun for someone in Montreal, Canada on December 22, we need to use the following formula:
Altitude = 90° - (latitude + declination)
First, we need to find the declination of the Sun on December 22. The declination of the Sun varies throughout the year and can be found in tables or calculated using formulas.
For December 22, the declination of the Sun is approximately -23.44°.
Now we can plug in the values:
Altitude = 90° - (46°N + (-23.44°))
Altitude = 90° - (46° + 23.44°)
Altitude = 90° - 69.44
Altitude = 20.56°
Therefore, the altitude of the Sun for someone in Montreal, Canada on December 22 at noon is approximately 20.56°.
