are these answers correct? 7/30/20 Lab-Assignment 20 Wave Speed Discussion Wave speed is how fast distance is propagated through. Frequency is how fast cycles are completed Wave speed is calculated as the space propagated through divided by time. Questions The number of cycles completed in a given space during a given time interval increases. Circle the correct answer below. [1] The wave speed increases / decreases / stays the same. The time in which the same number of cycles is...

3) Please circle the correct answers, if there is no correct answer, then leave it blank(do not circle 1. a) red light has a smaller wavelength and lower frequency than blue light. b) red light has a longer wavelength and higher frequency than blue light. 2. Since sound travels at about 340 m/s in air, we can see that a) electromagnetic waves travel at the same speed as sound. b) electromagnetic waves travel slower than sound if air is present....
3) Please circle the correct answers, if there is no correct answer, then leave it blank(do not circle.) 1. a) the velocity of electromagnetic waves increases with the frequency of the wave. b) the velocity of visible light waves is the same, however other types of electromagnetic waves has different velocities depending on the frequency. 2. a) as the wavelength of the wave increases, the frequency increases, and the velocity decreases. b) as the wavelength of the wave increases, the...

A device emits a sound wave in helium gas which then travels into standard air of the same temperature. If the speed of sound in helium is about three times the speed of sound in standard air, which of the following is true? The frequency of the sound is unchanged as the wave travels from helium to standard air while the wavelength increases. The frequency of sound decreases as the wave travels from helium to standard air while the wavelength...
A sound wave is known to have a frequency of 553Hz and a wavelength of 0.62m What is the velocity of the sound wave? Look up the speed of sound in air and write it down. Does the velocity you calculated agree with the known value for speed of sound in air?
[8] As light moves from air to water, its wave speed increases/decreases / stays the , same ? 19] As light moves from air to water, its wavelength incrcases, decrcass stays, the stays the [10] As light moves from air to water, its amplitude increases /decreases /stays the same
The relations between wavelength, frequency, period, and speed of propagation apply to all wave phenomena, not just electromagnetic radiation. The C key on a piano has a fundamental frequency of about 256 Hz. What is the corresponding wavelength of the sound waves? (The speed of sound in air varies with temperature but is about 340 m/s at room temperature.)
