What is the relationship between wavelength and frequency in sound waves?
Wavelength is inversely proportional to frequency in sound waves.
Wavelength is directly proportional to frequency in sound waves.
Wavelength increases as frequency increases in sound waves.
Wavelength and frequency are unrelated in sound waves.
What is the universal law of gravitation formula?
F = G * (m1 * m2) / r^2
F = m1 * m2 / G * r^2
F = G * m1 * m2 * r^2
F = G * (m1 + m2) / r

What happens to the speed of sound as the temperature increases?
The speed of sound increases as the temperature increases.
The speed of sound decreases as the temperature increases.
The speed of sound remains constant regardless of temperature changes.
The speed of sound is unaffected by temperature and only depends on humidity.
What is the effect of altitude on the speed of sound?
Altitude has no effect on the speed of sound.
The speed of sound increases with altitude due to higher temperatures.
The speed of sound is constant regardless of altitude changes.
The speed of sound decreases with increasing altitude due to lower temperatures.
How does the density of a medium affect the speed of sound?
Higher density always results in slower sound speed.
The speed of sound decreases with increasing density regardless of elasticity.
Density has no effect on the speed of sound.
The speed of sound generally increases with density if elasticity also increases.
