Answer:

F = 20.07 μN

Explanation:

given,                                            

intensity of sunlight = 667 W/m²

area of surface =  9.03 m²

speed of light = 3 x 10⁸ m/s

force = ?                                  

we know                                                                

force =intensity \times \dfrac{Area}{speed of light}

force =667 \times \dfrac{9.03}{3\times 10^8}

F = 20.07 x 10⁻⁶ N

F = 20.07 μN

Standing waves can ruin the acoustics of a concert hall if there is excessive reflection of the sound waves that the performers
Dmitrij [34]

Answer:

The answer to the questions is;

In terms of standing waves, the listener moves from a location with high amplitude to one with lower amplitude or vibration (anti-node to node)

The distance 4.1 cm is equivalent to λ/4

Explanation:

For standing waves we have is a stationary wave comprising of two opposite direction moving waves that have equal amplitude and frequency, resulting in the superimposition of the waves. As such certain points are fixed along the wave path that is the peaks amplitude of the wave oscillation is constant at a particular point. A node occurring at a point and an anti-node occurring at another fixed point

When the listener moves 4.1 cm he or she has left the anti-node to the node hence the faintness of the sound

The distance from the node to the anti-node is 1/4 wavelength, or 1/4×λ

Therefore 4.1 cm is λ/4
