identify the following statement.
1.Discovered radio waves by building devices that can produce and receive them. 2. He concluded that since light travels in straight lines, it must be a particle because waves are known to bend through obstacles. 3. The number of complete oscillations per second of energy in form of wave. 4. types of waves that are propagated by the use of any medium like air, water, rope, and other materials. 5. He hypothesized that light is an electromagnetic wave. 6. Made his first discovery of electromagnetism in 1821. 7. Explains that reflection is the bouncing of light on a surface, just like a bouncing ball.

1. Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna. When waves created by the sparks of the coil transmitter were picked up by the receiving antenna, sparks would jump its gap as well.
2. Theory of Sir Isaac Newton and the wave theory of Christian Huygens. Newton's corpuscular theory stated that light consisted of particles that travelled in straight lines.
3. The axis is called the period of the wave motion, and the number of oscillations executed per second is called the frequency. Wavelength is considered to be the distance between corresponding points on the wave—i.e., the distance between two adjacent peaks or troughs of the wave.
4. Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.
5. Light is a transverse, electromagnetic wave that can be seen by the typical human. In 1678, Christiaan Huygens (1629–1695) published Traité de la Lumiere, where he argued in favor of the wave nature of light.
6. Faraday made his first discovery of electromagnetism in 1821. He repeated Oersted's experiment placing a small magnet around a current-carrying wire and verified that the force exerted by the current on the magnet was circular.
7. Reflection is when light bounces off an object. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.
