Light travels slowest in high density media, faster in lower density media, and fastest in low density media.

Anit [1.1K]

Based on what we know, we can confirm that the wave behavior being observed when light passes through media of different densities is refraction.

<h3>What is refraction?</h3>

This is a term used to explain the behavior of light as it moves through distinct mediums. This behavior includes a change in direction of the light due to its change in speed.

Therefore, the wave behavior being observed when light passes through media of different densities is refraction.

A ball has a diameter of 3.77 cm and average density of 0.0839 g/cm3. What force is required to hold it completely submerged und

mestny [16]

Answer:

0.25 N

Explanation:

The density of the ball ( $\rho_b$ ) = 0.0839 g/cm³ = 83.9 kg/m³

The density of water ( $\rho_w$ ) = 1000 kg/m³

diameter = 3.77 cm = 0.0377 m

radius of ball = 0.0377/2 = 0.01885 m

The volume (V) = $\frac{4}{3} \pi r^3=\frac{4}{3}*\pi*0.01885^3=2.8*10^{-5}\ m^3$

Let us assume the acceleration due to gravity (g) = 9.8 m/s²

Hence:

The force is required to hold it completely submerged under water (F) is:

$F=\rho_w Vg-\rho_b Vg=1000*(2.8*10^{-5})*9.81-83.9*(2.8*10^{-5})*9.81\\\\$

F = 0.25 N

Consider a 7 m stretched string that is clamped at both ends. What is the longest wavelength standing wave that it can support (

user100 [1]

A vibrating stretched string has nodes or fixed points at each end. The string will vibrate in its fundamental frequency with just one anti node in the middle - this gives half a wave.

$l=\frac{\lambda }{2}$

Rearranging for the wavelength

$\lambda=2l$

$\lambda =2(7)$

$\lambda = 14m$

Therefore the longest wavelength standing wave that it can support is 14m
