a. An electron is accelerated towards a copper target anode with an accelerating voltage. It is stopped in a single impact. Write down an equation for calculating the minimum wavelength of the X-ray in terms of the accelerating voltage. Define all the terms in your equation. b. The magnitude of the accelerating voltage used in a. is increased. What happens to the (1) minimum wavelength of the X-ray radiation? (2) Intensity of the X-ray radiation?

a. λ=hc/E, where λ=wavelength of X-ray produced, h=planks constant, E=energy (eV) e is electron charge, c=velocity of light.b. (1) shorter wavelength, (2) intensity increases.

What are pyroclastic materials?

Pyroclastic material often appears during (or rather is a result of) a volcanic eruption. It consists of volcanic rock, ash, lava, and gases. These materials come in a cloud or a flow. The flow and the cloud are very hot and cause a lot of damage to people and areas...

What causes a tsunami?

Tsunami is a large amount of water that moves to the land. An earthquake that occurs in the ocean, as well as a big lake, makes large volumes of water move. A tsunami is often a series of huge waves.

List 3 important differences between P and S waves.

First difference is that P waves are faster than S waves.Secondly, S wave “involves oscillation perpendicular to the direction of propagation,” while P waves are characterized by compressional motion.Thirdly, P waves can travel through liquid, whereas S waves cannot do this.

Discuss the big bang theory and the evidence that supports it. Explain how some scientists regard it as an adequate explanation of the origin of the universe.

The Big Bang theory postulates that the Universe later expanded rapidly. The theory is supported by various pieces of evidence: for instance, the expansion, its early hot state, helium, and galaxy formation are derived from various cosmological models, including cosmic microwave background, Hubble diagram (type la supernovae), availability of light...

The study and analysis of light according to its component wavelengths is called

The answer is spectroscopy. Explanation: Spectroscopy is concerned with the exploration and analysis the electromagnetic spectrum of light. The electromagnetic spectrum is the term used to describe the variety of frequencies of electromagnetic radiation. Different wavelengths of electromagnetic waves produce various colors. Some of these colors can be seen by...
