Class 7 Light Extra Questions and Answers
Q: What is light? A: Light is a form of energy that makes things visible to our eyes. It travels in straight lines and at a speed of 3 x 10^8 m/s.
Q: What is rectilinear propagation of light? A: The rectilinear propagation of light refers to the fact that light travels in straight lines. This means that if there is no obstruction in the path of light, it will continue to travel in a straight line.
Q: What is the composition of white light? A: White light is composed of seven colors - violet, indigo, blue, green, yellow, orange, and red. This can be seen in a rainbow.
Q: What are the laws of reflection? A: The laws of reflection state that the angle of incidence is equal to the angle of reflection and that the incident ray, reflected ray, and the normal at the point of incidence all lie in the same plane.
Q: What is lateral inversion? A: Lateral inversion is a phenomenon where the left side of an object appears on the right side and vice versa when it is seen in a mirror. It occurs because the image is formed by the reflection of light.
Q: What is dispersion of light? A: Dispersion of light is a phenomenon where white light splits into its component colors when it passes through a prism. This happens because different colors of light bend at different angles when they pass through a prism.
Q: What is an erect image? A: An erect image is an image that appears upright and in the same orientation as the object it is formed from. It is formed when the object is placed beyond the focus of a convex lens or between the focus and the lens of a concave lens.
Q: What is Newton's disc? A: Newton's disc is a device that consists of a rotating disc with segments of different colors arranged in a specific order. When the disc is rotated, the colors blend together, forming white light.
Q: What is a spectrum? A: A spectrum is the range of colors that white light splits into when it passes through a prism. It includes the colors violet, indigo, blue, green, yellow, orange, and red.
Q: What is the path of light? A: The path of light refers to the direction that light travels in. It travels in straight lines and can be reflected, refracted, or absorbed by different surfaces.
These questions and answers are crucial for Class 7 students to understand the concept of light better and prepare for their exams. Additionally, practicing these questions will also help them reinforce their knowledge and improve their problem-solving skills.
Q: What is the speed of light? A: The speed of light is approximately 299,792,458 meters per second in a vacuum.
Q: What is rectilinear propagation of light? A: Rectilinear propagation of light refers to the straight-line motion of light in a homogeneous and transparent medium.
Q: What are the laws of reflection? A: The laws of reflection state that the angle of incidence is equal to the angle of reflection, and the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.
Q: What is lateral inversion? A: Lateral inversion refers to the phenomenon of a mirror image being flipped horizontally from left to right.
Q: What is an erect image? A: An erect image is an image that is oriented in the same way as the object that produced it.
Q: What is dispersion of light? A: Dispersion of light is the phenomenon of splitting white light into its component colors using a prism.
Q: What is a prism? A: A prism is a transparent object with at least two polished and inclined surfaces that refract light and split it into its component colors.
Q: What is the spectrum of light? A: The spectrum of light refers to the range of colors that make up white light, including red, orange, yellow, green, blue, indigo, and violet.
Q: What is Newton's disc? A: Newton's disc is a rotating disc that has seven colors of the spectrum arranged in a circle. When it is rotated at high speed, the colors blend to form white light.
Q: What are the effects of light? A: The effects of light include reflection, refraction, dispersion, and polarization.
Q: What is the path of light? A: The path of light refers to the trajectory that light follows as it travels through a medium.
Q: What is the composition of white light? A: White light is composed of all the colors of the spectrum, including red, orange, yellow, green, blue, indigo, and violet.
Q: What is the difference between concave and convex mirrors? A: Concave mirrors are curved inward, while convex mirrors are curved outward. Concave mirrors converge light rays to a point, while convex mirrors diverge light rays.
Q: What is the difference between a real and virtual image? A: A real image is formed when light rays converge and meet at a point, while a virtual image is formed when light rays appear to diverge from a point.
Q: What is the importance of light in our daily lives? A: Light plays a crucial role in our daily lives, as it enables us to see, communicate, and perform many tasks. It also has many practical applications, such as in medicine, technology, and entertainment.
