What is V in V 2pir T?
The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression 2•pi•R / T. It ends up that the acceleration is given by the expression v2 / R where v is the speed and R is the radius of the circle.
What is the wavelength range of electromagnetic radiation the human eye can detect CK 12?
light: Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has a wavelength in the range of about 380 nanometres to about 740 nm – between the invisible infrared and the invisible ultraviolet.
What is Blueprint in CBSE?
The CBSE class 10 blueprint 2022 contains all the subjects like Maths, Social Science, General Science, English, etc. Focusing on the weightage of marks and the important topics will make it easy to score good marks.
How will CBSE give marks?
As per the marking policy of CBSE, although the students will be evaluated out of a maximum of 100 marks for each subject, 20 marks will be submitted by schools and 80 marks will be from scores in exams held during the academic year.
What is V 2 in circular motion?
Centripetal acceleration The centripetal acceleration is the special form the acceleration has when an object is experiencing uniform circular motion. It is: ac = v2 / r. and is directed toward the center of the circle.
What is T 2pi sqrt l g?
The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
What is the wavelength range of electromagnetic radiation the human eye can detect?
380 to 700 nanometers
What is the visible light spectrum? The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
Which has a higher frequency microwaves or blue light?
Blue light has a shorter wavelength and therefore a higher frequency as compared to green light. Some reptiles can see light of shorter wavelengths than humans can see. Microwaves have a longer wavelength when compared to visible light.
What is Blueprint in science?
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey.
