Detailed explanation-1: -Electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible spectrum, ultraviolet waves, X-rays and gamma rays. It does not include alpha rays.

Detailed explanation-2: -The correct answer is Ultrasonic.

Detailed explanation-3: -Propagation of an Electromagnetic Wave Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves.

Detailed explanation-4: -The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Detailed explanation-5: -In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
