Well, Harry, what you said is not necessarily true the way you said it.
But we know what you mean, and what you meant to say is true.

The Doppler effect is observed if there is relative radial motion
between an object and an observer <em><u>AND</u></em> if the object happens
to be putting out sound or light in the observer's direction.

Sedaia [141]

Answer: Please find the answer in the explanation

Explanation:

Under what circumstances does distance traveled equal magnitude of displacement?

When a body's motion is linear in one direction. Or a body moving in a straight line without turning back.

What is the only case in which magnitude of displacement and distance are exactly the same?

When the body is moving in a straight line with without changing direction or without turning back.

Based electromagnetic spectrum? on its surface temperature of 6,000 K, most photons that leave the Sun's surface lie in which re

masha68 [24]

Answer:

option C

Explanation:

given,

Temperature of the surface = 6000 K

using formula to calculate $\lambda_{max}$

$\lambda_{max} = \dfrac{0.0029\ K.m}{T}$

$\lambda_{max}$ is the maximum wavelength emission in meter.

T is the temperature in kelvin.

$\lambda_{max} = \dfrac{0.0029}{6000}$

$\lambda_{max} = \dfrac{0.0029}{6000}$

$\lambda_{max} = 4.8333 \times 10^{-7}$

$\lambda_{max} = 4833\ A^0$

the wavelength is in Visible range

The Correct answer is option C
