What are the phenomenon that light travels on a straight line?
rectilinear propagation of light
The phenomenon that light travels in straight lines is called rectilinear propagation of light.
What are the types of natural phenomena?
Types of natural phenomena include: Weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, moonbow, blood moon and natural disasters such as electromagnetic pulses, volcanic eruptions, earthquakes, midnight sun and polar night.
What is the two laws of reflection of light?
Q23) State the two laws of reflection of light. Laws of reflection are: (i) The incident ray, the reflected ray and the normal ray at the point of incidence, lie in the same plane. (ii) The angle of incidence is equal to the angle of reflection.
What are the two natural calamities Class 8?
What are the two natural calamities? Answer: Lightning and. Earthquake.
What called natural phenomena?
Natural phenomena are those that occur or manifest without human input. Examples of natural phenomena include gravity, tides, biological processes and oscillation. Social phenomena are those that occur or exist through the actions of groups of humans.
What are the two laws of reflection are they same for plane mirror and two kinds of spherical mirror?
The incident ray,reflected ray and normal at the point of incidence lie on the same plane. Angle of incidence is always equal to the angle of reflection. No they are not same for the plane mirror and the two kinds of spherical mirror.
What are the two laws of reflection explain with diagram?
1. The incident ray, the reflected ray and normal at the point of incidence, lie in the same plane. 2. The angle of incidence is always equal to the angle of reflection (∠i = ∠r).
What do you mean by natural phenomena for Class 8?
A Natural Phenomenon is anything that occurs on its own in nature without any kind of human intervention. For example, the weather of a place, fog, storms, winds, tides, volcanic eruptions and cyclones all can be categorized as natural phenomena.
Where does natural phenomenon occur?
Phenomena are natural, but the disasters are produced by human action in his environment. For instance, the flooding of a flood plain caused by an overflowing river is a natural phenomenon; the presence of human settlements in the area creates the possibility of a disaster.
Is wind a natural phenomenon?
Weather phenomena can be defined as natural events that occur as a result of one or a combination of the water cycle, pressure systems and the Coriolis effect. They often involve or are related to precipitation, wind or heat.
Which phenomenon occurs due to the characteristic of light travelling in straight line?
Two natural phenomena that occur due to the characteristic of light travelling in a straight line are : A lunar eclipse that occurs when the Earth is situated between the Moon and the Sun. A solar eclipse that occurs when the Moon is situated between the Earth and the Sun.
What is the direction of light propagation called?
Usually light travels in a straight line. When we want to represent the propagation of light with a diagram, we represent it with the help of rays and beams. Ray A ray is a line with an arrow that shows the direction of propagation of light, and such a diagram is called a ray diagram.
What are the three properties of light?
What are the Properties of Light? 1 Light travels in a straight line. 2 The speed of light is faster than sound. Light travels at a speed of 3 x 10 8 m/s. 3 Reflection of light.
What phenomenon can only be explained by the particle nature of light?
There are few phenomenon which can only be explained by Particle Nature of Light whereas others are explained by Wave Nature of Light. Photoelectric Effect/Hertz Effect : This effect is based on the idea that the light is made up of series of particles called photons in which all photons have certain amount of energy.
