What happens to the energy of a wave when it is absorbed by a surface?

The energy of the wave is transferred to the particles in the surface, increasing their internal energy.

What is the term for the maximum distance of a point on a wave from its rest position?

Amplitude

What is the Big Bang theory, in relation to the origin of the universe?

The theory that suggests that the universe began from a very small region that was extremely hot and dense.

What is the difference between a convex and a concave lens in terms of their shape and effect on light?

A convex lens is thicker in the middle than at the edges and causes light rays to converge, whereas a concave lens is thinner in the middle than at the edges and causes light rays to diverge. Signup and view all the answers

What is the formula to calculate the density of a material, and how does it vary between different mediums?

The formula to calculate density is density = mass/volume. The density varies from one medium to another, depending on the mass and volume of the material. Signup and view all the answers

What is the difference between a longitudinal wave and an electromagnetic wave, and provide an example of each?

A longitudinal wave is a type of wave where energy moves parallel to the matter, whereas an electromagnetic wave is a transverse wave that transfers energy. An example of a longitudinal wave is sound, and an example of an electromagnetic wave is gamma radiation. Signup and view all the answers

What is the greenhouse effect, and how does it affect the Earth's surface temperature?

The greenhouse effect is when natural greenhouse gases stabilize the surface temperature of the Earth, allowing it to support life. It is enhanced as the atmospheric carbon dioxide concentration increases. Signup and view all the answers

What is the difference between an emission spectrum and a type of electromagnetic wave, and provide an example of each?

An emission spectrum is the specific wavelengths of light emitted by electrons in atoms as they lose energy, whereas an electromagnetic wave is a type of wave that transfers energy. An example of an emission spectrum is the spectrum of a specific element, and an example of an electromagnetic wave is infrared radiation. Signup and view all the answers

What is the focal length of a lens, and how does it affect the image formed?

The focal length is the distance from the lens to the principal focus. The focal length affects the image formed, as it determines the size and orientation of the image. Signup and view all the answers
