Background information about reflection and refraction of light

KIM [24]

Answer:

reflection :

angle of reflection and angle of incidence is equal
Incident ray and reflect d ray plus normal lies on the same plan on a same point
light reflect uniformly if it is incident on a plan surface

refraction :

light will refrect if light goes from rare medium to a dense medium or vice versa
after the light is refracted, it retunes to its original direction
angle of incidence is not equal to the angle of refraction

What is the wavelength of a wave with a frequency of 262 hz and a speed of 343 m/s

Tamiku [17]

Heya!!

For calculate wavelength, lets applicate formula:

$\boxed{\lambda = V/f}$

<u>Δ Being Δ</u>

f = Frequency = 262 Hz

v = Velocity = 343 m/s

$\lambda$ = Wavelenght = ?

⇒ Let's replace according the formula:

$\boxed{\lambda = 343\ m/s / 262\ Hz }$

⇒ Resolving

$\boxed{\lambda = 1,3 \ m}$

Result:

The wavelength is <u>1,3 meters.</u>

Good Luck!!

Drag the tiles to the correct boxes to complete the pairs. Match the sentences with the steps of the scientific method

Assoli18 [71]

Solution:

Make an Observation - An indoor plant in a dark room withers faster than the same plant in a room with ample sunlight.

Ask a question- Why do certain indoor plants die faster based on where they are placed in the house?

State a hypothesis- Sunlight is probably essential for plants to grow and live.

Run an experiment- Get two potted plants. Cover one with black paper. Place both plants outside in sunlight. See what happens to each plant after one week.

Analyze the results-The plant in the pot with black paper withered. The other plant was healthy.

Communicate the results to others - Plants need sunlight to make food so they can live.

Church organs have a set of pipes with different lengths. With those different pipes organs can produce sounds over a wide range

Paraphin [41]

Answer: The shortest possible wavelength of sound the organ can produce is 0.224 m

Explanation:

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light

c = speed of light = $331m/s$

As wavelength and frequency follows inverse relation, shortest wavelength is produced by highest frequency.

$\nu$ = highest frequency of light = $1.48kHz=1.48\times 10^3Hz=1.48\times 10^3s^{-1}$ $1Hz=1s^{-1}$

$\lambda=\frac{331m/s}{1.48\times 10^3s^{-1}}=0.224m$

Thus the shortest possible wavelength of sound the organ can produce is 0.224 m
