What is the speed of light in a vacuum?
300,000,000 m/s
250,000,000 m/s
873,000,000 m/s

James Clerk Maxwell first proposed this notion in the 19th century. According to this theory, light is described as a transverse wave composed of perpendicularly oscillating electric and magnetic fields.
(a)
He is a German scientist and experimenter who, through his electromagnetic wave demonstration, demonstrated that James Clerk Maxwell's prediction is true.
Albert Einstein
Friedrich Gustav Jakob Henle
Otto Hahn
Heinrich Hertz
According to the law of reflection, an angle of reflection equals an angle of incidence.
True
False
This wave is frequently linked to thermal scanning because they can detect heat. What wave is being described in this scenario?
(a)
It is an angle between the incident ray and the normal.
(a)
He is a Greek mathematician who came up with the law of reflection in about 300 BC.
(a)
In 1621, he made the initial discovery of the Law of Refraction. He was a Dutch astronomer and mathematician.
Antonie van Leeuwenhoek
Willebrord Snellius
Johannes Diderik van der Waals
Isaac Beeckman
Refraction is the term for the bouncing of a light wave as it strikes a surface.
True
False
These are light waves that are obvious to the naked eye. What light wave is this?
Visible Light
Radio Wave
Microwave
X-Ray
Used frequently in medicine to examine bones and joints to check for fractures and other diseases. It needs a higher frequency to penetrate through things since it can provide high-quality images for bone and joint detection. What light wave is this?
(a)
Electromagnetic waves move at different frequencies, yet light moves at the same speed regardless of the wavelength or frequency. What is being asked?
Electromagnetic Induction
Electromagnetic Spectrum
It is the separation between two consecutive in-phase wave points.
(a)
It is a measurement of how much the speed of light is slowed down when it travels through an optical medium and is symbolized by the letter n.
(a)
This wave has the shortest wavelength due to high frequency. What wave is this?
Gamma Rays
X-Rays
Ultraviolet Waves
This wave is commonly used to cook food. What wave is this?
(a)
This ray is created when light strikes a smooth surface and returns.
Reflected Ray
Incident Ray
Electromagnetic waves (EM waves) are characterized by three main properties. What are these properties?
Wavelength, Frequency, and Speed
Permittivity, Permeability, and Index of Refraction.
The formula for frequency is c = (λ)(v)
True
False
