Please help with with physics! Thank you very much for your time

1. Electromagnetic waves are examples of transverse waves. What is a transverse wave? (1 point)Oa wave that vibrates in a parallel direction to its motionOa wave that can move through a vacuumOa wave that travels at the speed of light cOa wave that vibrates in a perpendicular direction to its motion2. An electromagnetic wave travels through a vacuum. What is the ratio E to B of the wave? (1 point)Othe speed of light cO the frequency f of the waveOthe wavelength A of the waveOthe angle between g and g3. An electromagnetic wave of frequency 1021 Hz is best classified as(1 point)Oa gamma rayOa radio waveOvisible lightOa microwave
