One gets interference of the two waves on a screen in two-slit interference because:

A. The waves travel at different speeds.
B. The waves arrive at the screen at different angles.
C. the two waves travel different distances to reach the screen.
D. the waves have different frequencies.
E. the waves have different wavelengths.

E. the waves have different wavelengths

Explanation:

Light wave produced from two-slit diffracts from each slit, because the slits are narrow. These waves overlap and interfere constructively and destructively.

Again, if the paths taken by the two waves differ by any multiple of half-wavelengths (¹/₂, ³/₂, ⁵/₂ etc), then destructive interference occurs. Also, if the paths taken by the two waves differ by any whole number multiple of wavelengths (1, 2, 3, 4, etc), then constructive interference occurs.

Thus, one gets interference of the two waves on a screen in two-slit interference because the waves have different wavelengths

the results is a decrease in air temperature with an increase of altitude.
