Explanation:Let L be the length of organ pipe . For fundamental notewave length λ = 2LFrequency = velocity / λ300 = velocity / λvelocity in air= 300 x 2L= 600 LIn helium velocity changes as followsvelocity ∝ 1 / √molar massvelocity in helium =√ ( 28.8 / 4 ) x velocity in airvelocity in helium = 2.68 x velocity in airvelocity in helium = 2.68 x 600 LFrequency = velocity in helium / 2L= 2.68 X 600L / 2L= 804 Hz.For open organ pipe also increase will be 2.68 times only because the increase is due to change in the medium from air to helium .Reply

Explanation:
Let L be the length of organ pipe . For fundamental note
wave length λ = 2L
Frequency = velocity / λ
300 = velocity / λ
velocity in air= 300 x 2L
= 600 L
In helium velocity changes as follows
velocity ∝ 1 / √molar mass
velocity in helium =√ ( 28.8 / 4 ) x velocity in air
velocity in helium = 2.68 x velocity in air
velocity in helium = 2.68 x 600 L
Frequency = velocity in helium / 2L
= 2.68 X 600L / 2L
= 804 Hz.
For open organ pipe also increase will be 2.68 times only because the increase is due to change in the medium from air to helium .
