high

Explanation:

The resonant color of light that is 40 octaves above an F#4 at standard pitch A4=440 has a frequency of 406.81 THz. This color (drak red) has a wavelength of 736.93 nm. The frequency of an F#4 at standard pitch A4=440 is 369.99 Hz. At a temperature of 72°F (22.22°C), the speed of sound is 345.31 m/sec (1132.91 ft/sec). Under these conditions, an F#4 at standard pitch A4=440 has a wavelength of 93.33 cm (36.74 inches).

You can figure more out by using this equation

wavelength = speedOfLight / frequency
