When light is either reflected or refracted, the quantity that does not change in either process is its

Physics

Brrunno [24]3 years ago

Answer:

Frequency

Explanation:

When waves travel from one medium to another, it is only the frequency of the wave that remains constant . when a wave is refracted at the boundary between two media, the wave will slow down and its wavelength decreases. The wave usually bends at the interface between the two media. The wavelength and speed of a wave may change at the boundary between two media but its frequency remains the same.

Hence the frequency of light is its only property that remains constant.

Can someone help me please? I’ve been trying to solve these questions all day.
qwelly [4]

#16

If we put a resistor in circuit it will slow the speed of current

Let's check ohms law

\\ \rm\Rrightarrow \dfrac{V}{I}=R

  • So if resistance is more current is less

#17

Again use ohms law

\\ \rm\Rrightarrow V=IR

\\ \rm\Rrightarrow V\propto I

  • Voltage must be increased

A rocket initially at rest accelerates at a rate of 99.0 meters/second ^2.Calculate the distance covered by the rocket if it. At
Pani-rosa [81]

The distance covered is 1000 m

Explanation:

The rocket is moving by uniformly accelerated motion, so we can find the distance it covers by using the following suvat equation:

s=vt-\frac{1}{2}at^2

where

s is the distance covered

v is the final velocity

t is the time

a is the acceleration

For the rocket in this problem, we have:

v = 445 m/s is the final velocity

a=99.0 m/s^2 is the acceleration

t = 4.50 s is the time

Substituting, we find the distance covered:

s=(445)(4.50)-\frac{1}{2}(99.0)(4.50)^2=1000 m

Debora [2.8K]

A piece of wood is has a density of 0.6 g/cm3. when dipped in olive oil of density 0.8 g/cm3, 0.75 fractions of the wood is submerged inside the oil.

Fractions describe any number of parts of a whole, or more generally equal parts.In everyday English, fractions describe how many parts of a particular size there are. 8, 3/4.

In mathematics, fractions are used to represent proportions/parts of a whole. represent the same part of the whole. A fraction has two parts, a numerator and a denominator. The top number is called the numerator and the bottom number is called the denominator. A fraction is a part of a whole number and a way of dividing a number into equal parts. It is described as the number of equal parts counted (called the numerator) to the number of whole parts called the denominator. These numbers are separated by dashes.
