Which properties does a longitudinal wave lack

Longitudinal waves have all the same properties as transverse waves: speed, frequency, wavelength, and amplitude

What part of the electromagnetic spectrum does the ultrasonic wave falls into

An ultrasonic wave is not an electromagnetic wave; it is a sound wave.

An ultrasonic wave is not an electromagnetic wave; it is a sound wave.

An ultrasonic wave is not an electromagnetic wave; it is a sound wave.

An ultrasonic wave is not an electromagnetic wave; it is a sound wave.

What are three waves that need a medium

Sound waves, ocean waves and seismic (earthquake) waves need a medium

What is the focal length of a concave mirror that forms an image 25 cm from the mirror if the object distance is 20 cm

1/o + 1/i = 1/f

f = (o x i)/(o + i)

f = 11.1 cm (rounded)

What medium does sound wave travel faster in

Sound waves travel the fastest through a solid.
