It is part of the electromagnetic radiation spectrum, which is a form of energy.

Answer 1

Light

Question 2

These are those PROPERTIES OF LIGHT

Answer 2

• REFLECTION
• REFRACTION
• TRANSMISSION
• ABSORPTION

Question 3

Refers to the bouncing of light wave off the boundary

Answer 3

Reflection

Question 4

is the bending of light. It is an attraction between the molecules of the medium and the particles of light which contribute to the change of speed and direction as the particles of the light travel inside the medium

Answer 4

Refraction

Question 5

The change in the direction of a wave when it passes from one medium to another

Answer 5

Refraction

Question 6

Refers to the process where light passes through an object or medium without being absorbed.

Answer 6

Transmission

Question 7

Atoms contain electrons that can vibrate at certain frequencies.

Answer 7

Absorption

Question 8

When light waves strike an atom that has similar frequency, electrons will absorb the energy and will be set into vibration.

Answer 8

Absorption

Question 9

He proposed the wave theory of light.

Answer 9

Christian Huygens

Question 10

proposed the corpuscular theory of light in 1704. According to this theory, light consists of tiny particles or corpuscles coming from a luminous object.

Answer 10

Isaac Newton

Answer 11

Refrangibility

Question 12

It is a disturbance that travels through a medium or a vacuum and carries energy.

Answer 12

Wave

Question 13

is one in which the direction of energy transfer is perpendicular to the vibration of particles.

Answer 13

Transverse Waves

Question 14

It is the direction of energy transfer

Answer 14

Perpendicular

Question 15

One in which the direction of energy transfer or wave motion is parallel to the particle motion.

Answer 15

Longitudinal Waves

Question 16

is the distance between two identical points on a wave.

Answer 16

Wavelength

Question 17

It is a wave is the number of vibrations completed in one second,

Answer 17

Frequency

Question 18

consist of both electric and magnetic field waves.

Answer 18

LIGHT AS ELECTROMAGNETIC WAVE

Question 19

a Scottish physicist and mathematician, calculated that speed of the EM waves in a vacuum is approximately 𝟑 × 𝟏𝟎𝟖 𝒎/𝒔 which is the same as the speed of light.

Answer 19

James Clerk Maxwell

Question 20

The energy of an EM wave is a function of its frequency. In other words, the greater the frequency of an EM wave is, the energy is also greater.

Answer 20

ENERGY OF ELECTROMAGNETIC WAVES

Question 21

because frequency is inversely proportional to wavelength,

Answer 21

the energy of an EM wave is also inversely proportional to its wavelength.

Question 22

is the continuous range of electromagnetic waves arranged in order of frequency or wavelength

Answer 22

electromagnetic spectrum

Question 23

Splitting of white light into seven constituent colors when passed through the prism.

Answer 23

Dispersion

Question 24

is an optical element which is transparent with flat, polished surfaces that reflect light.

Answer 24

Prism

Question 25

the process where light rays deviate from its path due to non-uniformities in the medium through which they pass.

Answer 25

Scattering

Question 26

a phenomenon that occurs when two light waves meet while traveling along with the same medium.

Answer 26

Interference

Question 27

When waves combine to produce a wave with an amplitude higher than that of the original.

Answer 27

Constructive Interference

Question 28

occurs when two interfering waves are with opposite displacements.

Answer 28

Destructive Interference

Question 29

a process in which a light ray travels through an obstacle or around a barrier and it spreads out as a result.

Answer 29

Diffraction

Question 30

are elementary particles of light and are referred to as packets or bundles of energy.

Answer 30

Photons

Question 31

The emitted light has a certain wavelength that corresponds to different colors. It can be observed as a series of colored lines with black spaces in between. This is called

Answer 31

Atomic Spectra

Question 32

refers to the ejection of electrons from a surface of a metal in response to light directed to the metal.

Answer 32

Photoelectric effect

Question 33

He proposed that light consisted of individual photons, which interacted with the electrons in the surface of the metal.

Answer 33

Albert Einstein

Question 34

According to him electrons are emitted from a metallic surface when subjected to an incident light consisting photons.

Answer 34

Einstein
