How is light created physics?
Light is made up of photons, which are like tiny packets of energy. When an object's atoms heat up, photon are produced from the movement of atoms. The hotter the object, the more photons are produced.

Are physics hard?
In general, coursework at the college level is designed to be challenging. Physics is certainly no exception. In fact, physics is considered by most people to be among the most challenging courses you can take. One of the reasons physics is so hard is that it involves a lot of math.Jul 19, 2021
Is physics harder than chemistry?
Physics is the hardest major; it is harder than chemistry, biology, psychology, computer science, astronomy, biochemistry, and geology. The level of math and the number of abstract concepts in physics is unparalleled.Oct 26, 2021
Why do you choose physics as a career?
Physics helps you to understand the world around you, and satisfy your curiosity. Studying physics develops your critical thinking and problem-solving skills. Physicists are versatile, which opens a wide range of future careers.
Why should I major in physics?
Studying physics strengthens quantitative reasoning and problem solving skills that are valuable in areas beyond physics. Students who study physics or engineering physics are prepared to work on forefront ideas in science and technology, in academia, the government, or the private sector.
What is light wave?
1. A light wave is an electromagnetic wave that has both an electric and magnetic component associated with it. Electromagnetic waves are often distinguished from mechanical waves. The distinction is based on the fact that electromagnetic waves ______.
What does it mean when you see white?
When all the wavelengths of the visible light spectrum strike your eye at the same time, white is perceived. The sensation of white is not the result of a single color of light. Rather, the sensation of white is the result of a mixture of two or more colors of light.
What is the separation of light into its different colors called?
The separation of visible light into its different colors is known as dispersion. Each color is characteristic of a distinct wavelength; and different wavelengths of light waves will bend varying amounts upon passage through a prism. For these reasons, visible light is dispersed upon passage through a prism.
What is the narrow band of visible light?
This narrow band of visible light is affectionately known as ROYGBIV. Each individual wavelength within the spectrum of visible light wavelengths is representative of a particular color. That is, when light of that particular wavelength strikes the retina of our eye, we perceive that specific color sensation.
What is the wavelength of visible light?
This visible light region consists of a spectrum of wavelengths that range from approximately 700 nanometers (abbreviated nm) to approximately 400 nm.
What is electromagnetic wave?
As discussed in Unit 10 of The Physics Classroom Tutorial, electromagnetic waves are waves that are capable of traveling through a vacuum. Unlike mechanical waves that require a medium in order to transport their energy, electromagnetic waves are capable of transporting energy through the vacuum of outer space.
Which type of wave has a finite speed?
e. electromagnetic waves have an infinite speed and mechanical waves have a finite speed. See Answer. Answer: C. Electromagnetic waves are able to travel through a vacuum - a region void of matter. Mechanical waves require a medium in order to propagate from one location to another. 2.
How long is the free trial for a course?
Most courses come with a 30-day return policy or have a 7-day free trial.
Is physics a challenge?
Physics is the most fundamental of sciences learning it could be both a fun and a challenge. Fun since you get to know the workings of the world around you. Challenge because many a concept in Physics are challenging and can strain your cognitive tissues. Though an online course from a great tutor can easily mitigate this challenge.
Can you print a certificate in a course?
Yes, you will get a printable certificate in many courses. In fact, some course providers will ship a hard copy of the certificate to your desired address.
What is the color of light that we can see?
Our eyes are sensitive to a certain kind of light called visible light. Visible light is all the colors (red, yellow, blue, etc.) that we can see.
How fast do light waves travel?
These waves travel very quickly, about 186,000 miles (300,000kilometers) per second.
Is radio the same as light?
Radio waves are really the same as light. A radio is sensitive to this kind of light and turns it into music that you can hear. X-rays are also a kind of light. Doctors use a special kind of film to see x-rays when they shine through your body. Some animals, like bees can see ultraviolet light.
Can bees see ultraviolet light?
Some animals, like bees can see ultraviolet light. This is the kind of light that comes from a black light and also the light that causes sunburn when you stay outside too long. Light is a kind of wave, somewhat like ocean waves or sound waves. Waves carry energy from one place to another.
