Nature of Light
electromagnetic wave
What type of wave is light classified as?
The angle of reflection when a ray hits a mirror at an angle of 35 degrees from the normal.
The Law of Refraction
What is n1sin(theta)1 = n2sin(theta)2
The result when a ray of white light is incident on a prism
What is a spectrum?
The experiment Young created that supported the wave theory of light
What is Young's Double Slit Experiment?
Unlike sound, light does not require this to travel.
When the object moves 2m closer to a plane mirror, its image does this.
When does the image move 2m closer toward the mirror?
True or False: Frequency and Wavelength vary as light travels from one medium to another
False
The amount the ray is bent away from its original direction
The difference between specular and diffuse reflection
What is reflection from a smooth surface versus from a rough surface?
The scientist whose photoelectric effect experiment supported the particle nature of light.
Who is Albert Einstein?
This happens to the light when it goes from air into glass.
When does light bend closer to normal from one medium to the other?
This happens to the wavelength as light travels from glass to air
What is refraction, reflection, refraction
The physicist who explained many properties of light by proposing light as wave-like
Who is Huygens?
A beam of light enters glass and its speed decreases, but its frequency remains constant. This wave property must also decrease according to the wave equation.
After reflecting off two perpendicular mirrors, this happens to the direction of a light ray compared to its original direction.
What is it travels in the opposite direction?
The principle that can occur when light attempts to move from a medium with a high index of refraction to one with a lower index of refraction
What is Total Internal Reflection?
True of False: Yellow light deviates at a greater angle when refracting in a prism than blue light.
False
A light ray reflects off three plane mirrors arranged in a triangle and exits parallel to its original path. This must be true about the total change in direction caused by the reflections.
What is the net angle change of 0 degrees?
Shining higher-frequency light on a metal makes electrons come out with more energy, showing that light comes in energy packets instead of being continuous.
What are photons?
The complete reflection of light by the inside surface of a medium.
What is total internal reflection?
A light ray in air n1 = 1.00 is incident on a flat liquid surface at an angle of 42 degrees to the normal. If the refracted ray travels at an angle of 29 degrees to the normal, calculate the liquid's index of refraction and state whether it is moving into a "slower" or "faster" medium
What is 1.38 and slower?
The setup involving a source of light through a slit incident on a prism to observe separate wavelength of the ray of light.
What is prism spectrometer?
If you change the angle between two hinged mirrors from 60 degrees to 45 degrees, this is what happens to the number of images you see.
What is increase?
